Answer:
C) f(x) = tan^-1(x)
Step-by-step explanation:
The question is equivalent to asking which trig function passes the horizontal line test over the domain (-90°, 90°). Both the sine function and the tangent function are defined on that domain and pass the horizontal line test.
The inverse sine function has a range of [-90°, 90°] (with square brackets, signifying the end points are part of the range). The inverse tangent function does not have a range that includes ±90°, so is a better match for the range in the question.
Given:
This is an inequality. Normally when solving inequalities, we treat the inequality like an equal sign. Let's begin to solve. First, let's distribute on the left side. Multiply -2 by everything in the parenthesis:
Now, let's get the x on the left side of the inequality. It doesn't have to be on the left, but it is good practice when graphing inequalities. Add x to both sides. This will cancel the -x on the right:
Now, we need to get x all by itself. Let's add 4 to both sides which will cancel the -4 on the right side. We are now left with:
Now, since x cannot be negative, we need to divide both sides by -1. We are then left with:
NOTE: When dividing by a negative (or multiply by a negative fraction) to solve for x, you must FLIP the inequality at the end. This is why it is:
