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=[tex]\frac{2}{b-m}[/tex]
