Question 45870
Start with the basic equation "f(x)=x^2-7x+10" which is the frame-work for the problem.  Plug in the indicated value of "x" as indicated by "f(x)". 
. 
For example: f(0) means to substitute "0" for "x" within the equation and solve. 
a.) f(0)
f(x)=x^2-7x+10 [The frame-work]
f(0)=(0)^2-7(0)+10  [Substitute "0" for "x"]
f(0)=0-0+10 [Simplfy and solve]
f(0)=10 [Final answer]
.
.
f(x)=x2-7x+10
b.) f(5)
f(x)=x^2-7x+10 [The frame-work]
f(5)=(5)^2-7(5)+10  [Substitute "5" for "x"]
f(5)=25-35+10 [Simplfy and solve]
f(5)=0 [Final answer]
.
.

c.) f(1)
f(x)=x^2-7x+10 [The frame-work]
f(1)=(1)^2-7(1)+10  [Substitute "1" for "x"]
f(1)=1-7+10 [Simplfy and solve]
f(1)=4 [Final answer]
