what is the range if the domain is (-5,2,7) in the equation y=-2/3x+4

Question

what is the range if the domain is (-5,2,7) with the equation y=-2/3x+4.

Answer 1

The domain are values of x that satisfy the equation, then the range would be the corresponding values of y at the x-values of -5, -2, 7.

Therefore plug each value of x in the equation and evaluate to find the corresponding y-values. Those will be your range.

e.g., y = -2/3(-5) + 4 = 10/3 + 4 = 22/3
