Question 57880
Hi Sher,
  {{{f(x)=x^2-7x+10}}}; find (a) f(0), (b) f(5), and (c) f(-2).
substitute the values given for x and simplify:
(a)
{{{f(0)=(0)^2-7(0)+10}}}
{{{f(0)=0-0+10}}}
{{{f(0)=10}}}
(b)
{{{f(5)=(5)^2-7(5)+10}}}
{{{f(5)=25-35+10}}}
{{{f(5)=0}}}
(c)
{{{f(-2)=(-2)^2-7(-2)+10}}}
{{{f(-2)=4+14+10}}}
{{{f(-2)=28}}}
Happy Calculating, Sher!!!
