If F(x)=2x^2-7x+3

then f(2)=2(2)^2-7(2)+3
= 8-14+3
= -3

and f(-3)=2(-3)^2-7(-3)+3
=18 + 21+3
= 42

You just have to plug in the number they are giving you, then do the equation. Always remember your order of operations. I remember it as Please Excuse My Dear Aunt Sally (which is PEMDAS) Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Approximately how far will an object fall in 4 seconds, if it is thrown downward at an initial velocity of 20 meters per second (v0) from a helicopter? Formula is 4.9t^2+v04=s, t is the time in seconds, v0 is the initial velocity, and s is the distance in meters.
