: Evaluate each function for the value specified.
f(x) = x^2 - 7x + 10; find (a) f (0),(b) f (5), and (c) f (-2).
I need help with this, this is my first problem and I am confused. I have been trying to work this problem for two days. Any helps is appreciated. Thanks This question is from textbook Beginning Algebra

If f%28x%29+=+x%5E2-7x%2B10 evaluate:
a. f%280%29
b. f%285%29
c. f%28-2%29
All you do is just replace the x in the equation with the given value and work out the result:
a. f%280%29+=+0%5E2-7%280%29%2B10
f%280%29+=+10
b. f%285%29+=+5%5E2-7%285%29%2B10
f%285%29+=+25-35%2B10
f%285%29+=+0
c. f%28-2%29+=+%28-2%29%5E2-7%28-2%29%2B10
f%28-2%29+=+4%2B14%2B10
f%28-2%29+=+28
