Answer:

(3, 1)

Step-by-step explanation:

Midpoint of the diameter is the center

Since endpoints are (9, 7) and (-3, -5)

Midpoint will be:

((9 - 3)/2, (7-5)/2) = (3, 1)

So the center is (3, 1)

Write a quadratic equation in standard form with x-intercepts (-3, 0) and (4, 0) that passes through (2, -20).
jeka57 [31]

Answer:

The equation in standard form is: y=2x^2-2x-24

Step-by-step explanation:

Since they give you the x-intercepts (the zeros of the quadratic expression) one knows that the binomials: (x-(-3)) and (x-4) must be factors of the quadratic expression.

We can therefore write the equation as:

y=k\,(x+3)(x-4)

using the binomial factors given above, and a numerical factor "k" that we can determine by using the information that the graph passes through the point (2,-20):

y=k\,(x+3)(x-4)\\-20=k\,(2+3)(2-4)\\-20=k\,(5)(-2)\\-20=k\,(-10)\\k=\frac{-20}{-10} \\k=2

Then,the equation can be written as:

y=2\,(x+3)(x-4)\\y=2(x^2-x-12)\\y=2x^2-2x-24

where we wrote the equation already in standard form

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = 4 - x²

g(x) = 2x + 5

<u>Step 2: Find g(-2)</u>

  1. Substitute in <em>x</em> [Function g(x)]:                                                                         g(-2) = 2(-2) + 5
  2. Multiply:                                                                                                             g(-2) = -4 + 5
  3. Add:                                                                                                                   g(-2) = 1

<u>Step 3: Find f(g(-2))</u>

  1. Substitute in <em>x</em> [Function f(x)]:                                                                           f(g(-2)) = 4 - (1)²
  2. Evaluate exponents:                                                                                        f(g(-2)) = 4 - 1
  3. Subtract:                                                                                                            f(g(-2)) = 3
