Answer: D. Odd function
Step-by-step explanation:
x, -f(x) = f(-x)
First isolate x by multiplying by x on both sides. It will look like this:
(2/3)x=1.2
Then devise by (2/3) on both sides to get:
x= 1.2/(2/3)
The easiest way to get this is plug that into a calculator and get the answer:
x=1.8
Answer:
21+3x
Step-by-step explanation:
Expand this:
3(7+x)
So it becomes:
21+3x
I'd say the answer is 5 wins
hope this helps
