Let f(x)=4x2−5 . 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)=4x2−3 g(x)=8x2−10 g(x)=4(x+2)2−5 g(x)=8x2−5

to vertically strech a function, f(x) by a factor of c, that is cf(x)

so strech vertically by 2 means times whole thing by 2
so
2 times (4x^2-5) =8x^2-10

g(x)=8x^2-10
