We can   conclude that exponential function is a monotonous function and

depending upon the value of b the exponential function is either continuously increasing or continuously decreasing

On a coordinate plane, 2 curves mirror each other in quadrants 1 and 3

Step-by-step explanation:

A exponential function is one in which the variable appears in the exponent.

The common form of exponential functions is y=b^x where b is a positive number.

Where b >1 exponential growth occurs and where b<1, an exponential decay is observed.

Points (0,1) and (1,b) are always on the graph of the function y=b^x

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

Cost before sale tax=$46.00

Cost after including tax=$48.76

Sale tax=$48.76-46.00

=$2.76

we know,

sale tax=((sales tax rate)/100) * cost before sale tax

2.76=((sales tax rate)/100) *46.00

sale tax rate=(2.76*100)/46

                   =276/46

                    =6%

There fore sales tax rate=6%

Weight of adult elephant = 24,000 pounds

Weight of baby elephant = 260 pounds

Difference between weight = 24,000 - 260 = 23,740

Adult elephant weights 23,740 pounds more
