Question 123016: This question is from the textbook Hutchison, D., Bergman, B., Baratto, S., & Hoelzle, L. (2005). Beginning algebra (6th ed.). New
York: McGraw-Hill. (I do not have the actual book so no ISBN #)
The question is asking to evaluate each function for the value specified.
f(x)=Xsquared-7x+10; find (a) f(0), (b) f(5), and (c) f(-2).
I'm sorry but I don't even know how to start this one. Any explanation of the process would be helpful and very, very appreciated. Thanks!

a)
Let's evaluate f(0)
Start with the given function
Plug in
Raise 0 to the 2nd power to get 0
Multiply 1 and 0 to get 0
Multiply 7 and 0 to get 0
Subtract 0 from 0 to get 0
Add 0 and 10 to get 10
-----------------------------
b)
Let's evaluate f(5)
Start with the given function
Plug in
Raise 5 to the 2nd power to get 25
Multiply 1 and 25 to get 25
Multiply 7 and 5 to get 35
Subtract 35 from 25 to get -10
Add -10 and 10 to get 0
-----------------------------
c)
Let's evaluate f(-2)
Start with the given function
Plug in
Raise -2 to the 2nd power to get 4
Multiply 1 and 4 to get 4
Multiply 7 and -2 to get -14
Subtract -14 from 4 to get 18
Add 18 and 10 to get 28

f(x)=X^2-7x+10; find
(a) f(0) = 0^2-7*0+10 = 10
(b) f(5) = 5^2-7*5+10 = 0
(c) f(-2)= (-2)^2-7*-2+10 = 28
