Question

If f(x) = x2 - x + 2, then find the value for f(-3). can you please just solve the whole problem and show your work this is worth ten percent of my grade and if i fail i wil fail math i will fan you and give medals and mark you as best answer please
:(

Answer 1

We cannot just give you the answer....but here is a quick hint

f(x)
f(-3)

what's different between those two? well...-3...is in the place of x

so in terms of your equations

where you have

f(x)= x² - x + 2

f(3) = (-3)² - (-3) + 2

you literally just plug -3 in for every 'x' that you see...can you solve this?

Answer 2

Okay, here's the equation:
\[f(x) = x^2 - x + 2\]
You need to evaluate \(f(-3)\). To do that, you rewrite the equation substituting (-3) everywhere you see \(x\).

Answer 3

Remember, a negative number * a negative number gives you a positive number.

Answer 4

\[f(x) =x^2-x+2\]

Answer 5

f(-3)=(-3)^2 -(-3)+2
f(-3)=9+3+2
f(-3)=14

Answer 6

this is the answer..
write in order that I wrote..

Answer 7

f(-3)=(-3)^2 -(-3)+2
f(-3)=9+3+2
f(-3)=14 so 14 is the answer?

Answer 8

yes that is the exact answer.. trust :)

Answer 9

Yes, I agree that f(-3) = 14.

Answer 10

John showed you exactly what you needed to do, 40 minutes ago...
