Answer:
37
Step-by-step explanation:
f(x) = 2x-1
g(x) =x^2 +3
f°g(x) = means put g(x) in for x into the function f(x)
f(g(x)) = 2 (g(x)-1
=2(x^2 +3) -1
Distribute
= 2x^2 +6-1
=2x^2 +5
Now we let x=-4
f(g(-4)) = 2 (-4)^2 +5
=2(16) +5
=32+5
=37
What’s the point?
y=mx+b
m is the slope
y=5x+b then you substitute the point (x,y) on y and x to find b
X= can equal any number out of 1-9
Answer:
Step-by-step explanation:
x +3 I x⁴ + 0x³ - 6x² + 0x -28 I x³ - 3x² + 3x - 9
x⁴ + 3x³

-3x³ - 6x²
-3x³ - 9x²

3x² + 0x
3x² + 9x
