Consider function f.
Shkiper50 [21]

Answer:

  • f⁻¹(x) = 1/7x² + 3

Step-by-step explanation:

<h3>Given</h3>
  • f(x) = \sqrt{7x-21}
<h3>To find </h3>
  • Inverse of f(x)
<h3>Solution</h3>

<u>Change f(x) → x, and x → y, and solve for y:</u>

  • x = \sqrt{7y -21}
  • x² = 7y - 21
  • 7y = x² + 21
  • y = 1/7x² + 3

<u>y = f⁻¹(x)</u>

  • f⁻¹(x) = 1/7x² + 3

Solve x≤0 and x≥−4 and write the solution in interval notation. If there is no solution, type ∅.
xxTIMURxx [149]

The answer is (-∞.∞).

Draw out a number line. Plot 0 and -4 on the number line.

Shade to the left of x = 0, and have a filled in circle at the endpoint. This is the graph of x≤0

Then graph x ≥−4 by plotting a filled in circle at -4, and shading to the right.

Note how the two graphs overlap to cover the entire real number line

So if we have x≤0  or  x≥−4 then we're basically saying x is any real number. To write this in interval notation, we write (−∞,∞)

This is the interval from negative infinity to positive infinity (or just infinity). We exclude each endpoint because we can't actually reach infinity itself. Infinity is not a number. Infinity is a concept

Side note: if you change the "or" to "and", then the solution to x≤0  and  x≥−4 would be [-4, 0][−4,0] to indicate the interval from x = -4 to x = 0, including both endpoints. This is the region where the two graphs overlap.
