Question

If f(x) = x2 is vertically stretched by a factor of 17 to g(x), what is the equationof g(x)?O A. g(x) = 1772O B. g(x) = 77 3 x²O C. g(x) =G ***O D. g(x)= (17x)

Answer 1

Recall that function f(x) streched by a factor k has the form kf(x), then:

`g(x)=17f(x)`

Substituting f(x)=x² we get:

`g(x)=17x^2`
