Write a function g whose graph represents the indicated transformation of the graph f

Question

f(x)=2/3x^2+2 vertical stretch by a factor of 3

Answer 1

If we're stretching or shrinking the vertical, it means we're changing the y value. In other words, we're changing the output. So if we're stretching it by a factor of 3, that means every time we put in an x and get a y, that y is going to be three times bigger than it would otherwise be.

So what that means is, instead of f(x), we're going to get 3[f(x)]. So if you need to write the function, multiply your f(x) by 3...
