300
This word is used to describe a function whose graph is a straight line.
linear
300
Does the graph below represent a function?
What is No, not a function? It does not pass the vertical line test.
300
Evaluate the function for f(4)
f(x)=2x-5
f(4) = 3
300
Does the table represent a function?
No, the 2's in the domain repeat.
300
What is the domain of the table?
2, 3, 4
300
Which parent function matches with an equation that looks like y= x2?
What is a quadratic function?
400
This word is used to describe a function whose graph is NOT a straight line.
nonlinear
400
Does the graph represent a function?
What is No because it does not pass the vertical line test.
400

P(x)=-1/2x^2+5x+2
P(50)=-998
400
Does the mapping diagram represent a function?
Yes, the domain doesn't repeat. The range does but that still makes it a function.
400

-5, 0, 10
400
A straight line is what type of parent function?
A linear function
500
This is a relation with exactly ONE output for each input (working vending machine).
What is a Function?
500
Is this a function and why?
What is yes because it passes the vertical line test!
500

g(x)=-x^2+1
g(-3) = -8
500
1. Does the graph below represent a function?
2. What is the domain and range?
Yes, it passes the vertical line test.
Domain= -4, -2, 2, 3
Range= -3, -1, 2, 3
500
What is NOT another name for Domain?
a. input b. output c. independent variable d. x-values
b. output
This is Range, not domain.
500
Which equation matches the graph below?
a. y= x b. y= x2 y= y = |x|
b. It's a parabola which is a quadratic function so it has to have x2 in the equtaion.
