Question 90799


     evalute each function for the value specified:
f(x)= x (to the second power) - 7x +10, 
find (a) f(0), (b)f(5), and (c) f(-2)


  f(x) = x^2-7x+10

 a) f(0) = 0^2-7*0+10 = 0-0+10 = 10

 
 b) f(5) = 5^2-7*5+10 = 25-35+10  = 35-35 = 0


 c) f(-2) = (-2)^2-7(-2)+10 = 4+14+10 = 28


   f(0) = 10, f(5) = 0, and f(-2) = 28
