Answer:
The domain is
and its range is 
The y-intercept is (0,3).
Step-by-step explanation:
Consider the parent function
Its domain is
and its range is 
The graph of the function
is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the domain and will change the range of the function, thus the domain is
and its range is 
To find th y-intercept you have to find y at x=0:

Hence, the y-intercept is (0,3).
20.5 is his hourly pay rate
<span>f(x)=<span>x2</span>−1</span>That means to find the value of the function at any value of x, we square x and subtract 1. If <span>x=2a</span>, we square <span>2a</span> and subtract 1:<span>f(2a)=(2a<span>)2</span>−1=4<span>a2</span>−1</span>Now, we know that <span>f(2a)=35</span>so we can find the value of a:<span>f(2a)=(2a<span>)2</span>−1=4<span>a2</span>−1=35</span><span>4<span>a2</span>−1+1=35+1</span><span>4<span>a2</span>=36</span><span><span>a2</span>=9</span><span><span>a=±3</span></span>
