Answer:
1
Step-by-step explanation:
We have the function

and we want to know the value of
.
The first step is to find
; we can subtract 1 from it at the end! But what does
mean?
Basically, we're saying <em>"what is the value of the function when </em>
<em> ?"</em>
So, we simply replace
with 3 in the function, and we get:
.
Finally, we subtract 1 to find
.
Answer:
Option D doesn't make any sense.
Step-by-step explanation:
D) 7 hours of sleep correspond to an age of 19 years.
That is wrong.
If we use the expression provided

Good luck.
Answer:
Think about what domain and range is. Domain is the x and range is the y.
Step-by-step explanation: What values of x can you put in this function? Is there any number you cannot use?? Then what y's will you get back? The best way to find out might be to graph it to look. Since it is an even function whose ends go up, all the y's will be greater than or equal to the y value of the vertex.
