Question

If the parent function is y = 4^x, which is the function of the graph?

y = −2(4)^x

y = −3(4)^x

y = 3(4)^x

y = 2(4)^x

Answer 1

(c) y = 3(4)^x

Explanation:

The graph has a y-intercept of 3. This can help you determine which equation is the correct one.

__

The y-intercepts (y when x=0) of the offered equations are ...

(a) -2

(b) -3

(c) 3 . . . . . this is the correct equation

(d) 2
