f(-5) is x = -5

<u>Step 2: Evaluate</u>

  1. Substitute:                    f(-5) = -(-5)² + 10(-5) - 6
  2. Exponents:                   f(-5) = -(25) + 10(-5) - 6
  3. Multiply:                        f(-5) = -25 - 50 - 6
  4. Subtract:                       f(-5) = -75 - 6
  5. Subtract:                       f(-5) = -81

Four points from a line are shown in the table below.
Dvinal [7]

Answer:

Correct choice is D. y=-x+3.

Step-by-step explanation:

pick any two points from the table say (0,3) and (1,2)

Now we we can use both points to find the equation of line.

slope m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-3}{1-0}=\frac{-1}{1}=-1

now plug slope m=-1 and any point say (0,3) into point slope formula

y-y_1=m\left(x-x_1\right)

y-3=-1\left(x-0\right)

y-3=-1\left(x\right)

y-3=-x

y=-x+3

Hence correct choice is D. y=-x+3.
