1. ## Functions

Suppose a function f is defined as follows: You start with a real number x and add 3. Then you square the resulting number. Finally you multiply the resulting number by 4. Which of the following formulas represents f(x)?

a. f(x) = 4(x2 + 3)
b. f(x) = 4x2 + 3
c. f(x) = (4x + 3)2
d. f(x) = 4(x + 3)2

ok, the defintion's coming up, lets do what it says.

ok.

$x$

okie dokie

$x + 3$

Then you square the resulting number.
hmm, sounds crazy, but lets run with it

$(x + 3)^2$

Finally you multiply the resulting number by 4.
ok, you're the boss

$4(x + 3)^2$
