For the composite function FоG(X) = F(G(X)), just replace the function G(X) in the X of F(X):
F(X) = X + 4
G(X) = 3X² - 7
F(X) = X + 4
F(G(X)) = [G(X)] + 4
F(G(X)) = [3X² - 7] + 4
F(G(X)) = 3X² - 7 + 4
<h2>F(G(X)) = 3X² - 3</h2>
Answer:
B.y = 3x - 1
Step-by-step explanation:
Pick two points on the line
(0,1) and (2,5)
The slope using the slope formula
m = (y2-y1)/(x2-x1)
= ( 5-1)/(2-0)
= 4/2
= 2
We want a slope that is greater than 2
The slope intercept form of the equation is
y = mx+b where m is the slope
y = 3x - 1 has a slope of 3 which is greater than 2
Since a cube is l x w x h, find the length of one side first:
∛8,000 = 20
The length of one side is 20 feet. This can represented as "s".
To find the area of one of the faces, use s²:
20² or 20 x 20 = 400
The area of one face is 400 ft²!
