Answer:
Step-by-step explanation:
Apply the 30-60-90 formula
side between 60 and 90 is x
side between 90 and 30 is 
side between 90 and 30 is 2x
If =
then x=
Answer: 4. No, the graph is NOT a function because using the vertical line test, it intersects at two points at a time.
5. Yes, it is a relation, and it is also a function because once those points are plotted if given the vertical line test, there would not be two points crossed at once. So, yes, it is a function.
6. Yes, it is a relation. No, it does NOT make up a function because a vertical line would intersect all the points given.
The function family that each belongs to are :
a. linear = f(x)=x+2
b. exponential = f(x)=2^x
c. quadratic = f(x)=x^2
d. linear absolute value = f(x)=|2x|
A linear function should have either one or more variables without exponential form
A quadratic function should have either one or more variables with exponential form with degree 2
An exponential function has a variable raised to the power constant
A linear absolute contains a absolute value expression
