f(x) = x^{2} - 5

For the function shown, what is the range of the function when the domain is {2, 4, 7}?

**A){-1, 44}**

**B){-1, -5}**

**C){6, 21, 54}**

**D){-1, 11, 44}**

Factor the polynomial completely. x^{2} + 16

**A)(x + 4)(x + 4)**

**B)(x - 4)(x - 4)**

**C)(x + 4)(x - 4)**

**D)cannot be factored**

Given V = 2πr2h, solve for h

**A)h = V/2r ^{2}**

**B)h = V2πr ^{2}**

**C)h = V - 2πr ^{2}**

**D)h = V/2πr ^{2}**

f(x) = x^2 - 5

When the domain is 2, the range is -1

When the domain is 4, the range is 11

When the domain is 7, the range is 44

"D" is correct

x^2 + 16

The sum of two squares can never be factored in real number terms

V = 2*pi*r^2*h divide both sides by 2*pi* r^2

V / [ 2 * pi *r^2 ] = h = "D"
