Question

G(x)=3x^2-2x+7/2x+5
find g(-1)

Answer 1

g(- 1) = 4

Explanation:

To evaluate g(- 1) substitute x = - 1 into g(x)

g(- 1) =
`(3(-1)^2-2(-1)+7)/(2(-1)+5)` =
`(3+2+7)/(-2+5)` =
`(12)/(3)` = 4

Answer 2

= 22/3

Explanation:

G(x)=3x²- 2x+7/2x+5

When g is -1

= 3(-1)² - (2 (-1) + 7)/(2(-1) + 5

= -3² - (-2 +7)/(-2 + 5)

= 9 -(5)/3

= 9/1 - 5/3

The LCM is 3

= 27/3 - 5/3

= 22/3
