I need to evaluate the function on this problem for the value specified.
f(x) = x^2 - 7x + 10; find (a) f(0), (b) f(5), and (c) f(-2).
Thanks so much,

Hi Sher,
f%28x%29=x%5E2-7x%2B10; find (a) f(0), (b) f(5), and (c) f(-2).
substitute the values given for x and simplify:
(a)
f%280%29=%280%29%5E2-7%280%29%2B10
f%280%29=0-0%2B10
f%280%29=10
(b)
f%285%29=%285%29%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
Happy Calculating, Sher!!!

Hello Sher
to solve, substitute the numbers in for x
f(0)=0^2-7(0)+10.
f(0)=10
f(5)=5^2 - 7(5) + 10
f(5)=0
The last one follows the same line substitute in -2 for x, remember when squaring a negative number it comes out positive, and when subtracting a negative it is the same as adding a positive.
Try the last one for yourself, If you have any problems please feel free to email me.
good Luck
