Answer:
g(x) = ![5(2^{2x} )](https://tex.z-dn.net/?f=5%282%5E%7B2x%7D%20%29)
Step-by-step explanation:
If a function f(x) is vertically stretched by a factor of k, the new function we get in the form of k.f(x).
Rule to be followed,
y = k.f(x)
Where k > 1
If the function is vertically compressed then 0 < k < 1
Following the same rule,
A function, f(x) =
when vertically stretched by a factor of 5,
Transformed function will be,
g(x) = ![5(2^{2x} )](https://tex.z-dn.net/?f=5%282%5E%7B2x%7D%20%29)
