For the function defined by f(x)=3x^2+5x+2, find the following values.
(a) f(4)=
(b) f(x)=
(c) f(x)=
(d) f(x+h)=

For the function defined by...HELP 
Steve,
just plug and chug:
f(4) = 3(16)+5(4)+2 = 30
f(x) = 3(x)^2+5(x)+2 = 3x^25x+2
f(x) = (3x^2+5x+2) = 3x^25x2
f(x+h) = 3(x+h)^2+5(x+h)+2
= 3x^2+6hx+3h^2 + 5x+5h + 2
= 3x^2 + (6h+5)x + (3h^2+5h+2)
