Question

In quadratic functions:
f(x) = x^2
does 2f(x) = f(-2x)?

Answer 1

no

Answer 2

nope

Answer 3

correction does 2f(x) = f(2x)
when f(x) = x^2

Answer 4

no

Answer 5

still no

Answer 6

ok, for what x values is it different?

Answer 7

Try 3

Answer 8

2 f(x) would be 2x^2
f(2x) would be 4x^2

Answer 9

ok

Answer 10

i think i'm evaluating it incorrectly then

Answer 11

i tried 3 and got the same answers

Answer 12

2f(x), when x=3
2(3^2)

f(2x), when x=3
f(2*3^2)

Answer 13

f(x)=x^2
f(3)=3^2=9
2f(3)=2(9)=18
f(2x)=f(6)=6^2=36
18 does not equal 36

Answer 14

2f(x), when x=3
2(3^2)
2(9)
18

f(2x), when x=3
f(2*3^2)
(2*9)
18

Answer 15

ok ty
