Answer:
f = 9.25 (I think but maybe I read f(4) wrong)
Step-by-step explanation:
so f(4) means x = 4.
The new equation is
f(4) = 2x4 ^2 - 4 + 9
you first do 2x4^2. The minus 4. The add 9.
the answer to that is 4f = 37
Then solve
F = 9.25
4.5£
Exp:
18(.25) = 4.5
To convert % to decimal, always move the decimal 2 places to the left.
examples:
25% = 0.25
100% = 1.00
