40% change what i do is guess and check so i put in 15 • .4 + 15 and that gave me 21
F(x)=x² +2 —(1)
f[g(x)]=(g(x))² +2 —(2)
substitute the function g(x) into (2)
f[g(x)]= (1-3x)² +2
now x=-1
fg(-1)=(1-3(-1))² +2
=(1+3)² +2
= 16+2
= 18
I would answer but i dont understand a word you are saying ...
That is 0,3 pounds per hamburger for all 40 hamburgers he will make.at $2.25/ per pound you buy 12 pounds for $27.
12 pounds divided by 40 is 0.3 pounds. That's the weight in pounds of each meat in each hamburger.
Answer:
"The function is decreasing from x = −3 to x = −1."
Step-by-step explanation:
When looking at the first answer choice, we can definitely see that the function value ( g(x) ) is decreasing from x = -3 to x = -1.
At x = -3, the value is 17
At x = -1, the value is -3
So from 17 to -3, the value is really decreasing.
First answer choice is right.
<u>Note:</u> looking at the other choices, they aren't correct
