Functions of the form y = abx, where b > 0 and b ≠ 0, are called functions.

Exponential function.

Step-by-step explanation:

We are given that a function of the  form

Where and b>0

Exponential function: The function  is of the form

Where b is a  positive constant and greater than 0 and x is any real number.

The given function satisfied the define of exponential function.

Hence, the function of the form

Where b>0 and are called exponential function.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
