Dad Joke time:
What do baby parabola's drink?
Quadratic Formula!
y = 2x - 7
Start at y-intercept of (0,-7)
Go up 2 and right 1 to the point (1,-5)
Write an exponential function with a y-intercept 3 and a point (-1,9).
y = 3(1/3)x
Solve for x: 3x - 17 < 4x + 2
x > -19
(y3 * 2x3y) / y2
2x3y2

A camera shop charges $3.99 for an enlargement of a photograph. Enlargements can be delivered for a charge of $1.49 per order. Write an equation that gives the total cost of an order with delivery as a function of the number of enlargements.
y = 1.49x + 3.99
Solve x2 + 4x - 72 = 5
x = 7 and x = -11
2y-1*3x2y4

The parks and recreation department in your town offers a season pass for $90. As a season pass holder, you pay $4 per session to use the town’s tennis courts. Without the season pass, you pay $13 per session to use the tennis courts. Write a system of equations.
y = 4x + 90
y = 13x
x2 - 16x = -15
x = 15 and x = 1
2y-2 / yx-2 * y4 * (x-4)2
2x10 / y7
