Answer:
domain will be ( -∞, ∞)
Step-by-step explanation:
The given functions are f(x) = x² - 1 and g(x) = 2x - 3
We have to find domain of (fog)(x)
We will find the function (fg)(x) first.
(fog)(x) = f[g(x)]
= (2x - 3)²
= 4x² + 9 - 12x - 1
= 4x² - 12x + 8
= 4 (x² - 3x + 2)
The given function is defined for all values of x.
Therefore, domain will be ( -∞, ∞)

Answer:40%.
Since the student got 60% correct, the remaining percentage would be the part they got incorrect.
I got 60% by translating 9/15 into a decimal and moving the decimal point to create a percentage.
Hope this helps!
Step-by-step explanation:
let me know if the propositions they gave don't match with mine.

Considering the box and whisker plot, it is found that the number of dogs that weigh more than 35 pounds is given by:
C. 75
<h3>What does the box plot shows?</h3>
It shots the first quartile, the median and the third quartile. In this problem:
- The first quartile is of 35.
- The third quartile is of 70.
The first quartile of 35 means that 25% of the measures are less than 35, and 75% are more, hence, out of 100:
0.75 x 100 = 75
Which means that option C is correct.
