SOLUTION: Evaluate each function for the value specified.
f(x)=x^-7x+10; find (a) f(0), (b) f(5), (c) f(-2).
This is what I have: f(x)=2^(-7x+10)
(a) f(0)=2^(-7*0+10=2^(0+10)=2^+10=1024

Question 117574: Evaluate each function for the value specified.
f(x)=x^-7x+10; find (a) f(0), (b) f(5), (c) f(-2).
This is what I have: f(x)=2^(-7x+10)
(a) f(0)=2^(-7*0+10=2^(0+10)=2^+10=1024
(b) f(5)=2^(-7*5+10)=2^-25=1/(2*25)
(c) f(-2)=2^(-7*-2+10)=2^(14+10)=2*24
My question is, am I correct on these solutions?
Thank You, Barb Neely

Is your function ? If it is, then....
Let's evaluate
Start with the given function.
Plug in . In other words, replace each x with 0.
Evaluate to get 0.
Multiply -7 and 0 to get 0
Now combine like terms
-----------Now let's evaluate another value---------
Let's evaluate
Start with the given function.
Plug in . In other words, replace each x with 5.
Evaluate to get 25.
Multiply -7 and 5 to get -35
Now combine like terms
-----------Now let's evaluate another value---------
Let's evaluate
Start with the given function.
Plug in . In other words, replace each x with -2.
Evaluate to get 4.
Multiply -7 and -2 to get 14
Now combine like terms
