Question

If f(X)=3x^2-2, find (-3) (DOT) f(x)

a. -6x^2-6
b. 9x^2-6
c. -6x^2+6

Answer 1

So this would be
\[(-3) (3x^2-2) \]
\[or -3 * 3x^2 - 3 * (-2)\]

Answer 2

got it now?

Answer 3

yes! thanks

Answer 4

Its C.

Answer 5

how would you do

f(X)=5x-3 and g(X)=3x-3, find f(X)-g(X) the same?

Answer 6

group the like terms and subtract; Its (5x-3) - (3x-3)
=> 5x-3x - [3 -(-3)]
=>2x-6
