When x increases from a to a + 2, y increases by a factor of 16. for which functions is this statement true?
a) y = 2(4)x
b) y = 4x + 2
c) y = 2(16)x
d) y = 16x + 2

*note that all of the x's are exponents

(- 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 )

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
