Question

Evaluate for f(-2), show all your work:
f(x) = 3/2 x - 4

Answer 1

f(-2) = -7

Explanation:

f(x) = 3/2x - 4 f(-2)

f(-2) = 3/2(-2) - 4

f(-2) = -3 - 4

f(-2) = -7

Answer 2

The answer is:

⇨ f(-2) = -7

Work/explanation:

We should evaluate
`\sf{f(x)=3/2x-4}` for x = -2.

So I plug in -2:

`\sf{f(-2)=(3)/(2)*(-2)-4}`

`\sf{f(2)=(3)/(2)*\bigg(-(2)/(1)\bigg)-4}`

`\sf{f(-2)=(3)/(1) *-\bigg((1)/(1)\bigg)-4}`

`\sf{f(-2)=-3-4}`

`\sf{f(-2)=-7}`

Hence, the answer is f(-2) = -7
