6. prove that linear functions grow by equal differences over equal intervals. part l. this is the graph of y=-1/2x+10 use the graph to show equal intervals of x-values have equal differences of y-values. a) think about an interval on the axis starting with p + k. what is the difference between x-values? what is the difference between the y-values for these x-values? complete the table using y=-1/2+10. b) the difference in the x-values for each interval is this value is also constant because =-1/2(p+k)+/2p+10) =-1/2p-1/2k+10+1/2p-10 =-1/2k d) does

HELP I GIVE BRAINLIEST Follow the directions to convert the analog sound wave into a digital signal. The lines on the grid intersect at various points (x, y). For each whole-number value of x, find the intersection point that is closest to the wave. Draw a small circle on that point, and record its y-value. The circles for the x-values 0 through 3 are already done for you. Draw circles for the x-values 4 through 18. In a textbox, write down all 19 y-values obtained by sampling the wave.

y-values of sampled wave:

0, 5, 5, -3, -5, -3, 2, 0, 0, -1, -2, 1, 1, -1, -1, -2, 2, 3, -1

Explanation:

My teacher told me to put a dot on every cross or intersection the line is on.

Without graphing, tell which statements are true for the graph of the function y = x2 + 2. i. all points on the graph are above the origin. ii. all points on the graph have positive x-values. iii. all points on the graph have positive y-values. statements and are true. statement is true because x^2 is non-negative for all values of x, so the minimum value of x^2 is 0. thus, the minimum y−value for the function is and the lowest point on the graph is (0, which is above the origin. statement is true because the lowest point on the graph is (0, so

Which statement describes the end behavior of the exponential function f(x) = 2x – 3? a for very high x-values, f(x) moves toward positive infinity. b for very high x-values, f(x) moves toward negative infinity. c for very high x-values, f(x) moves toward the horizontal asymptote. d for very low x-values of x, f(x) moves toward negative infinity.

Step-by-step answer

The correct answer is a. for very high x-values, f(x) moves towards positive infinity.

This can always be determined by two factors.

1) is it linear or something else?

2) Is the lead coefficient positive or negative.

In this case, since the x is not being raised to a power or is not raised to a power itself, we know that there are no asymptotes. That takes care of #1 for us.

As for #2, since the coefficient of x (which is the highest power here) is positive, that means it continues to get bigger. If it were negative it would be the opposite. So, the correct answer is that as x gets bigger, f(x) moves towards positive infinity.

Consider the two functions shown here. Which function grows faster for large positive values of x? [Note: Function 1 is shown in the graph.] A) Function 1, because it has larger x values than function 2. B) Function 1, because the y-value for x = 1 is greater in function 1. C) Function 2, because all the range values of the function are positive. D) Function 2, because the y-values increase faster than the y-values in function 1.

D) Function 2, because the y-values increase faster than the y-values in function 1.

Step-by-step explanation:

"Function 2, because the y-values increase faster than the y-values in function 1. The values in the table are being squared, while the ones in the graph are from the linear function y = 4x + 5."

Part 1: the table below displays a small portion of the infinite domain of the exponential function y = 2x. use the values for the domain to determine its corresponding range. x -2 -1 0 1 2 y part 2: graph the exponential function y = 2x. using the table from part 1. part 3: think about it: a. in the table of domain and range values, we used -2 as our minimum x-value. are there values of x for the function that are less than -2? b. locate the smallest y-value on your table. compare it with the y-values of your graph. is the table a complete representation
