This word is used to describe the set of all inputs for a function.
What is the domain?

What is YES! NO input values repeat.
Write the equation of this line.
y= 2/3 x + 0
f(x) = x2 - 2x find f(3)
3
State the slope and y-intercept.
9x - 2y = 6
slope = 9/2
y-intercept = -3
This word is used to describe the set of all outputs for a function.
What is the range ?
Is this a function and why?

What is no, because x's repeat at 8?
g(x) = 5x + x2 , find g(4)
36
Find the DOMAIN:
{(-2, 4), (3, 2), (2, 10)}
What is {-2, 3, 2}?
Daily double: You can bet up to 600 points on...... This word describes a relation that pairs each x-value with only one y-value.
What is a function?
This graph is not a function.
What is Graph 1?
f(x) = x2 - x , find f(-6)
42
Write the point slope form of the equation that goes through (5, -6) and (-3 , 12)
y + 6 = -4/9(x - 5)
OR
y - 12 = -4/9(x + 3)

60 km/h
g(x) = 9x2 - x , find g(-2)
38
Write the equation of the line in slope-intercept form. (Make sure it is FULLY simplified.)
(-2,-1) and (1,2)
y = x + 1
What is special about the rate of change of a linear function?

58

What is the RANGE of the situation?
{0,20,40,60,80,100,120}
The largest y-value of a function.
What is a maximum?
Is (2,5), (3,6), (4, 7) and (-3,6) a function?
YES
f(x) = 3x2 + 4x
g(x) = 6 - 4x
Find g(f(-1))
22
