you just plug in the numbers for x and solve. For example: f(-2) = 5(-2) + 2 = -10 + 2 = -8
OpenStudy (anonymous):
I dont get how to do this other one. f(x)=-1/3x+1
OpenStudy (anonymous):
f(3)=5(3)+2=17 f(7)=5(7)+2=37
OpenStudy (anonymous):
f(-1/2)=5(-1/2)+2=-3
OpenStudy (anonymous):
Just substitute the numbers in for x and do the math. -1/3(PutYourNumberHere) + 1
