## samtab 2 years ago 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 :(

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?

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 \(x\).

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

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

5. cahit

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

6. cahit

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

7. samtab

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

8. cahit

yes that is the exact answer.. trust :)

9. whpalmer4

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

10. whpalmer4

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

11. samtab

thanks that ewas just alot more simple lol:)

12. whpalmer4

Yeah, simpler because he did the whole thing for you, violating the OpenStudy code of conduct...
