Tripp swims 50 laps a day in hopes of becoming a collegiate
swimmer. Write an equation to
represent y, the total number of
laps Tripp has swam after x
days.

y = 50x

Step-by-step explanation:

[-2, 7) ∪ (7, ∞)

Step-by-step explanation:

Given function is,

f(x) =

This function is defined only when

[Since square root of a number is not defined]

4x ≥ -8

x ≥ -2

And denominator is greater than of equal to zero.

(If the denominator of a fraction is zero, fraction is not defined)

x - 7 ≥ 0

x ≥ 0

Therefore, domain of the given function will be,

[-2, 7) ∪ (7, ∞)
