Answer:
It's cosine.
Step-by-step explanation:
Cosine is Adjacent / Hypotenuse.
Answer:
11
Step-by-step explanation:
Replace the variable xx with −1-1 in the expression.
f(−1)=−3⋅−1+8f(-1)=-3⋅-1+8
Simplify the result.
Tap for fewer steps...
Multiply −3-3 by −1-1.
f(−1)=3+8f(-1)=3+8
Add 33 and 88.
f(−1)=11f(-1)=11
The final answer is 1111.
=11

Answer: No, this isn't a function.</h3>
Why not? Focus on the two points (0,2) and (0,4)
We have the x value x = 0 show up twice. Any time x repeats itself like this, it leads to "not a function" as the result.
In other words, the input x = 0 leads to multiple outputs y = 2 and y = 4 at the same time. A function is only possible if every x input leads to exactly one y output.
If you are a visual learner, then plot all of the points on the same xy grid. Then notice how (0,2) and (0,4) fail the vertical line test to show we don't have a function.
Side note: The y values can repeat themselves in a function.
