You are given the exponential function g(x) = 3 x . Which option below gives the formula for a new function h created by stretching g by a factor of 3 along the y-axis?


h(x) = 3x+1

h(x) = 3x-1

h(x) = x · 3x+1

h(x) = x · 3x-1

Answer:

A. [tex]h(x) = 3^{x+1}[/tex]

Step-by-step explanation:

Stretching means that original function is multiplied by a constant, which is equal to 3 in this case:

[tex]h(x) = 3 \cdot g (x)[/tex]

[tex]h(x) = 3\cdot 3^{x}[/tex]

[tex]h(x) = 3^{x+1}[/tex]

The answer is A.
