Given two points: f(0)=6 f(5)=28
Which are these points:
(0,6) (5,28)

And told to use equation f(x)=Pa^x

Find P
Then find a

Where do I plug the given points into?

For the point (0, 6), substitute 0 for x and 6 for f(x):
f(x) = P * a<SUP>x</SUP>
6 = P * a<SUP>0</SUP>

From this, you should be able to find the value for P.

Then, use the point (5, 28). Substitute 5 for x and 28 for f(x)....and replace P with the value you just found. Now, you should be able to solve for "a".

You can plug in a lamp or a microwave....but you substitute a value for a variable (sorry....just a pet peeve of mine!)
 
Mrspi,

Screw your pet peeves! I came here for help in math, not English. I came here for HELP, not to be ridiculed. And why would you apologize after being an ass??? Are you trying to say, "Sorry, I'm such a butt munch. I can't help myself."
 
\(\displaystyle \L
\begin{array}{l}
f(x) = Pa^x \\
f(0) = Pa^0 = P = 6 \\
f(5) = Pa^5 = 28 \\
\end{array}\)

I wish I had read your totally juvenile response to Mspi before posting.
She is trying to be helpful!

In this case, at this site, in happens to be English.
In that bothers you, please do not return.
