Question

Describe the transformation required to change y=x^2 into: y=2(x+7)^2-7

Answer 1

Work from the inside out.
1. (x+7) this shifts all x values left 7 units.
2. (...)^2 the squared then describes a parabola.
3. 2(...) the 2 coefficient steepns the parabola
4. the -7 shifts the graph down 7 units.

Answer 2

the answer is given by substitute

Answer 3

Thanks a lot mate :)

Answer 4

oh sorry, didnt read the question, so you want to shift graph 7 left, steepen it by factor 2, and shift it down 7 units, since you started with x^2 haha sorry shoudl learn to read xD
