Question

The graph of g(x)g(x) ​​is the graph of f(x)=8x+20f(x)=8x+20 stretched horizontally by a factor of ​4​.


Which equation describes the function g?

​A g(x)=8x+5g(x)=8x+5 ​
B​ g(x)=32x+20g(x)=32x+20 ​
C​ g(x)=2x+20g(x)=2x+20 ​
D g(x)=2x+5

Answer 1

B. g(x)32+20


You solve that by : f(4x)
f(4)(8)+20
