Question

I'm trying to figure out out to graph this function f(x)=-2x^4

I already have these points
-2,?
-1,-2
0,0
1,-2
2, ?
I can't figure out the ones with the question marks ?? Help??

Answer 1

Replace every x with -2
\[\Large f(x) = -2x^4\]
\[\Large f({\color{red}{x}}) = -2({\color{red}{x}})^4\]
\[\Large f({\color{red}{-2}}) = -2({\color{red}{-2}})^4\]
\[\Large f({\color{black}{-2}}) = ???\]
