1. find the domain and range
{(0, 0), (1,−,−,−,−16)(1,−,−,−,−16)

2. suppose f(x)=2x−5. find the value of f(3)

3. write an equation of the line in standard form with the given slope through the given point.
slope = -3 and (0,0)

4. for the direct variation, find the constant of variation. then find the value of y when x = 2
y = 4, x= 0.5

5. write an equation of the line with the given slope and y-intercept. use slope – intercept form.
m = 3, b = 5

1. Find the domain and range

{(0, 0), (1,−1),(2,−4),(3,−9),(4,−16)(1,−1),(2,−4),(3,−9),(4,−16)

Domain:{0,1,2,3,4}

Range: {0,−1,−4,−9,−16}

2. Suppose f(x)=2x−5. Find the value of f(3)

1 is your answer

3. Write an equation of the line in standard form with the given slope through the given point.

Slope = -3 and (0,0)

y=mx+b.

y=−3x

4. For the direct variation, find the constant of variation. Then find the value of y when x = 2

Y = 4, x= 0.5

5. Write an equation of the line with the given slope and y-intercept. Use slope – intercept form.

M = 3, b = 5

m=

you need a common difference between consecutive terms to be constant, like 1,2,3,4 or 2,4,6,8, or 1,3,6,9
