Determine whether the relation is a function and why:
1) (1,-2) , (2,1), (3,6) , (4,13) , (5,22)
2) (7,4) , (5,-1), (3,-8) , (1,-5) , (3,6)

Simplify. show your work. ( 6x-2 ) ^2 ( 0.5x )^4

Match each function with the corresponding function formula when h(x)=5-3x and g(x)=-3+5

To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1
