Question

Given f(x) evaluate f(-2)

Answer 1

Answer: f(-2) = 29

Explanation:

To evaluate this function for f(-2), we will substitute -2 for x into the given function.

Given:

`\displaystyle f(x)=6x^2-3x+(2)/(x)`

Substitute:

`\displaystyle f(-2)=6(-2)^2-3(-2)+(2)/(-2)`

Square and divide:

`\displaystyle f(-2)=6(4)-3(-2)-1`

Multiply:

`\displaystyle f(-2)=24+6-1`

Combine like terms:

`\displaystyle f(-2)=29`
