Answer:
<em>A= 1256</em>
Step-by-step explanation:
<u>The formula for area of a circle is </u>
1. Diameter is DOUBLE of radius, so the diameter must be divided by 2. <em>40/2 = 20. </em>
<em>2. </em>Then, plug in the values into the area formula. <em>A= 3.14</em>
3. Solve.<em> A= 1256</em>. (Remember that 20 squared is <em>20x20</em>)
As for the domain, the only restriction comes from the logarithm. The argument of a logarith must be strictly positive, so we have

As for the range, we have:
- The range of
are all real numbers - If we change to
we're translating the function horizontally, so the range remains the same - If we change to
we're stretching the function horizontally, so the range doesn't change - If we change to
we're translating the function 1 unit up, but the range is already all the real numbers, so it doesn't change.
