If a function f(x) is stretched vertically by a scale factor of k, then

The new function is k . f(x)

Since the given function is


f(x)=x^2

Since the new function is


g(x)=5x^2

Then k = 5

f(x) is stretched vertically by a scale factor of 5

The correct answer is

The base graph vertically stretched by a factor of 5

The first choice
