Hello.
So, you should already know that to find the inverse of a function you switch x and y and solve.
For f(x) = x² + 3, it's domain is all real numbers, and the range is y ≥ 3.
The inverse of f(x), it is
, and the equation is = ±√(x - 3). It's domain is x ≥ 3, and the range is all real numbers.
There are many unique characteristics about inverses, like the values of x and y are switched, it's reflected on the line y = x, and the domain and range is switched.
So your final answer is c. f(x) domain: all real numbers, range: y ≥ 3
domain: x ≥ 3, domain: all real numbers.
Hopefully it makes sense! :)

Answer:
The number of single-shot espressos sold by the cafe was 49.
Step-by-step explanation:
It is provided that Addison's Cafe offers two kinds of espresso: single-shot and double-shot.
Total number of espressos sold by the cafe yesterday afternoon was,
<em>N</em> = 70
The proportion of single-shot espresso sold was, <em>p</em> = 0.70.
Let <em>X</em> = number of single-shot espressos sold.
Compute the number of single-shot espressos sold by the cafe as follows:
Thus, the number of single-shot espressos sold by the cafe was 49.
