Step-by-step explanation: Mathematics

option 4

Step-by-step explanation:

Given the x- intercepts say x = a, x = b, x - c then the corresponding factors are

(x - a), (x - b), (x - c) and the polynomial is the product of the factors

Here the x- intercepts are x = 3, x = 0, x = - 1, thus the factors are

(x - 3), (x - 0), (x - (- 1) , that is

(x - 3), x and (x + 1) , then

y = ax(x - 3)(x + 1) ← where a is a multiplier

To find a substitute (1, - 8) into the equation

- 8 = a(1 - 3)(1 + 1) = - 4a ( divide both sides by - 4 )

a = 2, thus

y = 2x(x - 3)(x + 1) ← expand factors using FOIL

= 2x(x² - 2x - 3) ← distribute by 2x

= 2x³ - 4x² - 6x

(B) Draw a graph that joins the points (100, 135) and (500, 375) and has a slope = 0.6

Step-by-step explanation:

1. They gave us two points

(100, 135)

(500, 375)

2. We find the formula

(375, 135)

(500,100) which is 0.6

~~Hope this helps~~

D is false

Step-by-step explanation:

f(x) = -2x2 + 4x + 6 should be written with a " ^ " to indicate exponentiation:

f(x) = -2x^2 + 4x + 6.

Because of the - sign, we know that the graph of this function opens down, so there is a maximum at the vertex.  We can determine the x-value at the vertex by using the formula x = -b/(2a), which here is x = -4/(2*-2), or 1.

Evaluating f(x) = -2x^2 + 4x + 6 at x = 1, we get -2 + 4 + 6, or 8.  So statement A is true:  there's a max at (1, 8).  This is also the vertex of the graph.

Let's now look at C and D.  We evaluate f(x) at x = 3 and x - 2.  If the output (y) value is 0, we know we have an x - intercept:

f(3) = -2(9) + 4(3) + 6 = 0.  Yes, C is true, (3, 0) is an x-intercept.

f(-2) = -2(4) - 8 + 6 is not 0.  Therefore D is false; (-2, 0) is not an x-intercept.

Look at B:  Let x = 0 and find y:  it's 6.  Thus, (0, 6) is the y-intercept.  B is true.

(4x +1)(x +6)

Step-by-step explanation:

The other answer choices have the correct first and last term of the given trinomial, but the x-term is incorrect.

(4x +1)(x +6) = 4x² +25x +6 . . . . . correct choice

(4x +6)(x +1) = 4x² +10x +6

(2x +3)(2x +2) = 4x² +10x +6

(2x +6)(2x +1) = 4x² +14x +6
