f%28x%29=x%5E2-7x%2B10
(a) f(0)
plugin x=0 in the equation
f%280%29=%280%29%5E2-7%280%29%2B10
f%280%29=10
(b) f(5)
plugin f(5) in the equation we get
f%285%29=+%285%29%5E2-7%285%29%2B10
f%285%29=+25-35%2B10
f%285%29=0
(c) f(-2)
plugin x=-2
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
