Slope from a table
Graphing Linear Equations
100
Function or Relation? Explain
Relation, because the x-value of 0 repeats and goes to two different y-values.
100
Find the Domain and Range.
Domain: {-3,-2,-1,0,1}
Range:{-3,-1,0,1,2}
100
Evaluate the function when x=-2 and x=3
f(x)=-3x+8
f(-2)=-3(-2)+8=14
f(3)=-3(3)+8=2
100
Find the slope from the table.
m=(3-5)/(-2--1)=2
100
Find the slope and y-intercept then graph the equation.
y=-1/4x-1
slope=-1/4;"y-intercept"=-1
200
Function or Relation? Explain.
Function, there are no repeating x-values.
200
Find the Domain and Range.
Domain:{-2, -1, 0, 1}
Range: {-3, -2, 0, 1}
200
Evaluate the function when x=-1 and x=6
g(x)=2x^2-5
g(-1)=2(-1)^2-5=-3
g(6)=2(6)^2-3=67
200
Find the slope from the table.
m is undefined.
200
Find the slope and y-intercept then graph the equation.
y=-3x-3
slope=-3/1;"y-intercept"=-3
300
Function or Relation? Explain
Relation, the x-value of 1 repeats and goes to 2 different y-values.
300
Find the Domain and Range.
Domain: All Real Numbers
Range: y>=0
300
Find the value of x so that the function has the given value.
g(x)=3/2x-1;g(x)=-7
-7=3/2x-1
-6=3/2x
x=-4
300
Find the slope from the table.
m=0
300
Find the slope and y-intercept then graph the equation.
y=4
slope=0;"y-intercept"=4
