Answer: D
<u>Step-by-step explanation:</u>
f(x) = 2x g(x) = x² - 1
f(g(x)) = 2(x² - 1)
= 2x² - 2
g(f(x)) = (2x)² - 1
= 4x² - 1
Answer:
{31, 0, 28, -27} are integers
{2pie, 25square root 3, 3.141592653..., square root 48} are irrational numbers
{
$79.75*0.2= 15.95
$79.75-15.95= $63.80
63.80+15.95= $79.75
Answer= $15.95
Line parallel to y=x+11 so slopes are equal then
y= x+b
Passing through the point C (-6;2) then C belongs to this line
yc=xc+b
b= 6+2
b= 8
So y intercept is equal to 8
