Question 1113543
 the function f(x) = 3 – x^2 to find 
 a. f(-2)
f(-2) = 3 - (-2^2)
f(-2) = 3 - 4
f(-2) = -1
:
b. f( 2/3 )
{{{f(2/3) = -3 -((2/3)^2)}}}
{{{f(2/3) = -3 - 4/9)}}}
{{{f(2/3) = -3}}}{{{(4/9)}}}
:
 c. f(a + 2) 
{{{f(a+2) = -3 - (a+2)^2}}}
FOIL(a+2)(a+2)
{{{f(a+2) = -3 - (a^2+4a+4)}}}
{{{f(a+2) = -3 - a^2-4a-4}}}
{{{f(a+2) = -a^2 - 4a  - 7}}}
