Question

Determine if the function is even, odd or neither
f(x)=-3x^2+4

Answer 1

Even

Answer 2

can you show your work please

Answer 3

AND THIS ?? f(x)=2x^3−4x

Answer 4

f(x) = f(-x) ?

-3x^2+4 = -3(-x)^2+4

(-x)^2=x^2 because (-x)(-x)=x^2

Answer 5

To check if a function is even, substitute in -x for x and see if the resulting function is the same as the original

Answer 6

CAN YOU DO THE SECOND PLEASE??

Answer 7

f(x)=2x^3−4x is odd

Answer 8

CAN YOU SHOW ME THE STEPS @larryboxaplenty

Answer 9

what happens to the -3 in the first question?

Answer 10

-f(x) = f(-x) ?

-(2x^3-4x) = -2x^3+4x = f(-x) = 2(-x)^3-4(-x) = -2x^3+4x

Answer 11

ok thanks.
but can you answer my question above ^

Answer 12

Even function: f(x) = f(-x) ?

Odd function -f(x) = f(-x)?

Answer 13

f(x)=2x^3−3x^2−4x+4??
