Answer:

(f o g)(x) = 4x^2 - 8

Step-by-step explanation:

(f o g)(x) = f(g(x))

f(x) = x^2 - 8

g(x) = 2x

f(g(x))

f(2x) = (2x)^2 - 8

       = 4x^2 - 8

(f o g)(x) = 4x^2 - 8

Line CD contains points A (4, 6) and B (4, 3). The slope of line CD is (2 points)
Nadya [2.5K]

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = A(4, 6) and (x₂, y₂ ) = B(4, 3)

m = \frac{3-6}{4-4} = \frac{-3}{0}

Division by zero is undefined thus the slope of CD is undefined

How do I graph y greater than equal to 5
Hatshy [7]
On your graph, draw a horizontal line at y=5. Basically a line over (-3,5) to (3,5) or whatever the greatest x's are. Since it is greater than or equal to, it is a solid line. Greater than, you shade above the line
