Question

Graph the quadratic functions y = -2x2 and y = -2x2 + 4 on a seperate piece of paper. Using those graphs, compare and contrast the shape and position of the graphs.

Answer 1

is your function looks like
\[\huge y=-2x ^{2}\]and\[\huge y=-2x ^{2}+4\]

Answer 2

yes

Answer 3

for \[y=-2x ^{2}\] your graph will be a parabola(little compressed) but reflected about x-axis

for\[y=-2x ^{2}+4\]your graph will be same as upper graph with 4 units shifted in +y direction.

DOES IT HELP?

Answer 4

yes thank you very much

Answer 5

you are ever welcome.
