Question 89328


    Find the indicated function values? 
a)g(x)= x-5 g(5)
b)f(x)=3xsquared + 5x f(0)
c)f(x)=4xsquared + 3x-2 f(-1)

  a) g(x) = x-5

     g(5) = 5-5 = 0  hence g(5) = 0

  b) f(x) = 3x^2+5x
     f(0) = 3*0^2+5*0 = 0+0 = 0     hence  f(0) = 0

  c) f(x) = 4x^2+3x-2
     f(-1) = 4*(-1)^2+3(-1)-2 = 4*1-3-2 = 4-5 = -1  hence f(-1) = -1
