f(x) increase by a factor of 3
Explanation:
Given that f(x)= 3* and the interval is x=4 to x=57
Now we put the value for x is 4 to 57 then value of f(x) increase with the multiply of 3.
Because the x is multiplied with 3 i.e., 3*
So f(x) increase by a factor of 3.
If we put x=4, then f(x)= 12 (∵ 3×4=12)
If we put x=5, the f(x)= 15 (∵ 3×5=15)
If we put x=6,the f(x)= 18 (∵ 3×6=18)
similarly., values of x= 7,8,9,...155.
Then,
If we put x=56, the f(x)=168
This process will continue until f(x)=171 for x=57.
Answer:c
Step-by-step explanation:
<u>Find amount spent on magazines:</u>
1 magazine = $3.95
3 magazines = $3.95 x 3 = $11.85
<u>Find amount spent on books:</u>
Amount spent on books = $47.65 - $11.85 = $35.80
<u>Find number of books:</u>
Number of books = $35.80 ÷ $8.95 = 4
Answer: Huge bought 4 books
Answer:
(-4, -1/2)
Step-by-step explanation:
Just by looking at the graph I can estimate that the midpoint of AB is (-4, -1/2) but we can also use midpoint formula to get a for sure answer.
Midpoint Formula: <em>((x1 + x2)/2, (y1 + y2)/2)</em>
x: (-5 + (-3))/2
-8 / 2
x = -4
y: (-4 + 3)/2
-1 / 2
y = -1/2
