(q3) decide if the function is an exponential growth function or exponential decay function, and describe its end behavior using limits. y=7^-x

Choice D is correct

Step-by-step explanation:

We are given the exponential function;

Using the law of exponents the function can be re-written as;

The base 1/7 is less than 1 hence this represents an exponential decay function.

For any exponential decay function y;

as x approaches infinity, y will always tend to 0

as x approaches negative infinity, y will always tend to infinity

step-by-step explanation:

we have

using a graphing tool

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

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