Question

Using x= -2,0,2 to generate a table of values for y= 1/2x^2 + 3 will give you y values of -5,-3,7

Answer 1

The right values of y :

5 , 3 , 5

Explanation:

Let f be the function of equation : y = 1/2x² + 3

then f(0) = 1/2(0)² + 3 = 0 + 3 = 3

f(2) = 1/2(2)² + 3 = 2 + 3 = 5

f(-2) = 1/2(-2)² + 3 = 5
