A(t) = $$1350(0.8)^t$$ ; Attendance on September 7th is 442

A(t) = $$1350(0.2)^t$$ ; Attendance on September 7th is 442

$$y=(x+2)^2+3$$

$$y=(x-3)^2+2$$

$$y=(x+3)^2-2$$

$$y=(x-3)^2-2$$

Both roots are greater than zero.

The sum of the roots is 15.

One root is zero, and the other root is greater than zero.

One root is less than zero, and the other root is greater than zero.

$$b(x) = -x^2 + 4x - 1$$

$$b(x) = x^2 - 4x + 1$$

$$b(x) = -x^2 - 4x + 1$$

$$b(x) = x^2 + 4x - 1$$

y = $$(\frac{9}{4})x^2$$ , y = $$2x^2$$ , y = $$(\frac{5}{4})x^2$$ , y = $$(\frac{1}{2})x^2$$

y = $$(\frac{1}{2})x^2$$ , y = $$(\frac{5}{4})x^2$$ , y = $$2x^2$$ , y = $$(\frac{9}{4})x^2$$

$$(9/4)x^2$$ , $$(5/4)x^2$$ , $$2x^2$$ , $$(1/2)x^2$$

y = $$2x^2$$ , y = $$(1/2)x^2$$ , y = $$(5/4)x^2$$ , y = $$(9/4)x^2$$

$$-5x^2 - 4x - 3$$

$$-5x^2 + 20x - 27$$

$$-5x^2 + 20x - 13$$

$$-5x^2 - 4x - 11$$

$$4g^2+9g-3$$

$$10g^2+1g+1$$

$$4g^2+1g+1$$

$$10g^2+9g-3$$

Perimeter = 2(length + width) = 2[(2x) + (x-1)] = 2(3x-1) = 6x-2

Perimeter = 2(length + width) = 2[(2x) + (x-1)] = 2(3x-1) = 3x-2

Perimeter = 2(length + width) = 2[(2x) + (x-1)] = 2(3x-1) = 4x-1

Perimeter = 2(length + width) = 2[(2x) + (x-1)] = 2(3x-1) = 5x-2
