Use the given Domain to find the range of function:
f(x)=-2x^2+7, D={2, -3, 0}

R = {15, 25, 7}

Step-by-step explanation:

the domain of the function has the values of x for which the resulting values in y form the range.

simply put the values 2, -3 and 0 one by one in the equation and the respective values of y you get will be the range

f(2) = 2(2)² + 7

f(2) = 8 + 7

f(2) = 15

f(-3) = 2(-3)² + 7

f(-3) = 2 × 9 + 7

f(-3) = 18 + 7

f(-3) = 25

f(0) = 2(0)² + 7

f(0) = 7

the underlined values form the range of the function

hence

range R = {15, 25, 7}

answer: x=3 and y=4
