What is the equation of a parabola that has a vertex of (-1, 4) and that is 2 times narrower than f(x) = x2, where the vertex is a minimum?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
