Let f(x)=4x^2−5

A new quadratic function g(x) is the function f(x) stretched vertically by a factor of 2.

What is the equation of this new function g(x)?

Question 5 options:

g(x)=4x^2−3

g(x)=8x^2−10

g(x)=4(x+2)^2−5

g(x)=8x^2−5

Respuesta :

FLORC
since it is being vertically stretched f (x) will be multiplied by 2
so
2 (4x^2-5)
distribute
8x^2-10 is g (x)

g (x)=8x^2-10
