Question

F(x) = x^2 is stretched vertically by a factor of 4 and shifted 1 unit down.

equation = ???

Answer 1

f(x) = 4x² - 1

Explanation:

The given function is; f(x) = x²

Now, when stretched vertically by a factor of 4, we have;

f(x) = 4x²

It's now shifted 1 unit down.. Thus, the final function will be;

f(x) = 4x² - 1
