Question 62732
Plug in the value .... since you were given three different values ... you need to work it 3 times.
1. {{{ f(x) = x^2 – 7x + 10 }}}
{{{ f(0) = 0^2 – 7(0) + 10 }}} 
{{{ f(0) = 0 - 0 + 10 }}}
{{{ f(0) = 10 }}}
2. {{{ f(x) = x^2 – 7x + 10 }}}
{{{ f(5) = 5^2 – 7(5) + 10 }}}
{{{ f(5) = 25 - 35 + 10 }}}
{{{ f(5) = -10 + 10 }}}
{{{ f(5) = 0 }}}
3. {{{ f(x) = x^2 – 7x + 10 }}}
{{{ f(-2) = -2^2 – 7(-2) + 10 }}}
{{{ f(-2) = 4 + 14 + 10 }}}
{{{ f(-2) = 18 + 10 }}}
{{{ f(-2) = 28 }}}


In essence, what we have created here is an X,Y table or a set of three ordered pairs

(0,10) (5,0) (-2,28)
