Answer:

f(-4) = 72, f(x + 5) = 3x² + 23x + 36

Step-by-step explanation:

f(-4) = 3(-4)² - 7(-4) - 4

      = 48 - (-28) - 4

f(-4) = 72

f(x + 5) = 3(x + 5)² - 7(x + 5) - 4

           = 3(x + 5)(x + 5) - 7(x + 5) - 4

           = 3(x² + 10x + 25) - 7(x + 5) - 4

           = 3x² + 30x + 75 - 7x - 35 - 4

f(x + 5) = 3x² + 23x + 36

Which equation represents the graphed function?
dezoksy [38]

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = \frac{0+3}{2-0} = \frac{3}{2}

note the line crosses the y- axis at (0, - 3) ⇒ c = - 3

y = \frac{3}{2} x - 3 → C

How do you find the M.A.D to any equation
torisob [31]

Steps to finding the M.A.D

1. Find the mean of the data!

   - all all the numbers up and divide by how many numbers there are

2. Find the absolute value of the difference between each data value and the mean:

     |data value – mean|.

3. Find the sum of the absolute values of the differences

4. Divide the sum of the absolute values of the differences by the number of data values.

I hope I helped! Tell me if this is confusing or not :)
