Answer:
B. f(x) domain: x ≥ 1; f⁻¹(x) range: y ≥ 1
Step-by-step explanation:
The <em>domain</em> of a function is identical to the <em>range</em> of its inverse. This is reflected in choices B and D. However, f(x) is undefined for x < 1, so it makes no sense to restrict its domain to x ≤ -2, as in choice D.
The appropriate response is ...
B.
- f(x) domain: x ≥ 1
- f⁻¹(x) range: y ≥ 1
12*123.9=1486.8

Answer:
yes
Step-by-step explanation:
it was very complicated for me but i got it bc i alr did that before
What you should do for this casp is to use the given expression and clear the value of x.
We have then:
y = 1.245x - 3.684
Clearing x:
1.245x = (y + 3.684)
x = (y + 3,684) / (1,245)
Substituting the value of y:
x = ((40) +3,684) / (1,245) = 35.09
x = 35
answer:
the best estimate of the number of songs that Marquis purchased is 35
