Given: f(x) = x² + 7
Let y = x² + 7
x = y² + 7 (since the inverse is reflected about the y = x line, the coordinates are interchangeable)
y² = x - 7
y = √(x - 7)
Thus, the inverse function f^(-1)x = √(x - 7)

Answer:
<em>Leila would make a profit of $48</em>
Step-by-step explanation:
~ Knowing that there is some sort of proportion that can be formed through Leila and Jo's profit, we could form even a proportionality to compute the profit Leila makes given jo's profit of $60 ~
<em>If is is known that Leila: Jo, 4: 5, we could form such a proportion:</em>
4 5 ⇒ where x - Leila's profit knowing Jo's profit of $60
x 60
<em>Now let us solve for x, through cross multiplication:</em>
5x = 60 * 4,
5x = 240,
x =<em> profit of $48</em>
