HELP! HELP! HELP! A function and its inverse are shown on the graph. Which answer pairs a possible domain restriction for f(x) a
Svetradugi [14.3K]

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

Marquis wrote the linear regression equation y=1.245x - 3.684 to predict the cost, y, of x songs purchased. Marquis spent $40 on
jasenka [17]
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
