The domain and range of a function is the set of input and output values, the function can take.

  • <em>The domain is [0,6]</em>
  • <em>The range is [0,90]</em>

<em />

From the question, we have:

\mathbf{Rate = \$15}

<u>The domain</u>

He cannot mow more than 6 yards a day.

This means that the domain is: 0 to 6

<em>This is properly represented as: [0,6]</em>

<u></u>

<u>The range</u>

When he mows 0 yards, his earnings is:

\mathbf{Earnings = 0 \times \$15 = \$ 0}

When he mows 6 yards, his earnings is:

\mathbf{Earnings = 6 \times \$15 = \$ 90}

This means that the range is: 0 to 90

<em>This is properly represented as: [0,90]</em>

Oliga [24]

Answer:

x = 2 1/3

y = 14 / (2 1/3) = 14 / (7/3) = 14*3/7 = 42/7 = 6

y = 6

x = 4 1/5

y = 14 / (4 1/5) = 14 / (21/5) = 14*5/21 = 70/21 = 3 7/21 = 3 1/3

y = 3 1/3

x = 7/6

y = 14 / (7/6) = 14*6 / 7 = 12
