Answer:

The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular x value. The y value of a point where a vertical line intersects a graph represents an output for that input x value.

Answer:

The answer is d

Step-by-step explanation:

I graphed it

-b/2a to get the vertex

3x^2-12+9

-(-12)/(2)(3)=2

plug in 2 to the function

12-24+9=-3 which is the y value on the graph

(2,-3) is the vertex

1.25s+y=t
a= fair admission
1.25s=amount spent on tickets for rides
t=total
Example
1.25*25+y=t
31.25+y=43.75
y=12.50
If you multiply the price of the ride tickets by the amount bought then subtract it from the amount spent total you get the admission price. You can use this equation for anyone who only pays for the rides and fair admission
