Question

Given the function g(x)= 2x2+6 find the indicated value

Answer 1

g(-10) = 206, g(-1) = 8, g(
`(1)/(2)`) = 6.5

Explanation:

Step 1; Take the values given as values of x. The values of x are -10, -1 and
`(1)/(2)`. We substitute these values in the function g(x). In the function g(x) we substitute the values of -10, -1,
`(1)/(2)` in the place of x in g(x). So for g(-10) we substitute the value of -10 in the place of x and get g(-10). Similarly, we do for the other two values and find g(-1) and g(
`(1)/(2)`).

Step 2; Substituting the values in the function we get

g(-10) =
`2(-10)^(2)` + 6 = 2(100) + 6 = 206

g(-1) =
`2(-1)^(2)` + 6 = 2(1) + 6 = 8

g(
`(1)/(2)`) =
`2(1)/(2) ^(2)` + 6 = 2
`(1)/(4)` + 6 = 0.5 + 6 = 6.5.
