Find the range of the function for the domain {−3, 1, 4.5}. f(x) = 2x2

{2, 18, 40.5}

Step-by-step explanation:

Only 3 x-values are given here:  {-3, 1, 4.5}.  We will find the corresponding y values using the function f(x) = 2x^2:

f(-3) = 2(-3)^2 = 18

f(1) = 2(1)^2 = 2

f(4.5) = 2(4.5)^2 = 40.5

Thus, the range corresponding to domain {-3, 1, 4.5} is {2, 18, 40.5}.

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)
