Answer:
Step-by-step explanation:
You could do this one of 2 ways. First is to look at the graph and locate x = 0. That is the y-axis. ON the y axis, the cosine curve is at a y value of 1. Second way is to go to your calculator and, in degree mode, hit cos(0) and you'll see that it is 1.
Because domain restrictions apply to this rational expression, x cannot be equal to {-2, 2}.
<h3>What is domain?</h3>
Domain restrictions are any points in the domain where the function will not have a value. This basically means that there is a point in the function where x will not work.
For the numerator, any value of x will suffice. We can have a value of 0 in the numerator, or a positive, negative, or decimal number.
However, the denominator cannot be equal to zero. This is due to the fact that a fraction bar represents division, and we cannot divide by zero.
Here,
x²-4=0
Add 4 to both sides:
x²-4+4 = 0+4
x² = 4
Take the square root of both sides:
√x² = √4
x = 2 or x = -2
The x cannot be equal to {-2, 2} as domain restrictions apply to this rational expression.
