How do you find f(2x) when you know f(x) = x^3?

1 answer:

6 0

To find the answer, you just plug 2x in place of x (even though 2x already has an x). It would look something like this: f(2x)= (2x)^3 = 2x*2x*2x= 8x^3

$P=2l+2w$
$P=2(\frac{x}{6}-1)+2(x)$
$P=\frac{2x}{6}-2+2x$
$P=\frac{x}{3}-2+2x$
$P=2\frac{1}{3}x-2$

Sophomore: (B-) + (C+) + (A-) +(A-) /4

(2.66 + 2.33 + 3.66 + 3.66)/4 = 12.31/4= 3.0775

All: (3.245 + 3.0775)/2=6.3225/2=3.16125
