Question

A function is described by the equation y=2x2 - 5x-3, in which y is dependent on x. If a value for the independent variable is selected from the set {-3,0,1,3,4}, which of the following is a corresponding dependent value?

Answer 1

put one by one x=-3,0,1,3,4
one i tell U
y=2x2-5x-3
y=2(-3)2-5(-3)-3
=2*9+15-3=18+15-3=30

Answer 2

y=2(0)^2-5(0)-3=0-0-3=-3
