Find f(-3), f(-1), and f(1)

suter [353]

Answer:

I will just show you how to substitute.

Step-by-step explanation:

all you have to do is just plug f(x) into the number you want. So if you see any x's, all you gotta do is plug that number after f for x.

So an example of an equation for one of your number is:

$f\left(x\right)=x^2+x$

you then want to plug the number after f for the x's. (I'm doing f(-3).

$f\left(-3\right)=\left(-3\right)^2-3$

You then should get the equation above.

after that you solve.

$f\left(-3\right)=9-3$

$f\left(-3\right)=6$

just follow these steps and you should be fine :))

Solve the equation. –x + 8 + 3x = x – 6

saul85 [17]

First group the coefficients together on their side of the equal sign.
-x + 3x = 2x.

Then, since it is a positive number, subtract it from that side and the other side.

On the other side, the x becomes -x.

Add the 6 from the other side to the 8 to make 14.

14 = -x

Divide both sides by -1, to get the answer.

x = -14
