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 :))

How to find amplitude and period from equation?

polet [3.4K]

If your graph is a COS or SIN graph :

$y = a \sin(bx) + c$
a is the Amplitude
and period is:
$\frac{360}{b}$

If your graph is a TAN graph :
$y = a \tan(bx) + c$
A TAN graph has no amplitude as it has no Maximum or Minimum value.
To find period :
$\frac{180}{b}$
