Answer:
The vertex is
Step-by-step explanation:
For a general quadratic function the form is:
For the function
Take common factor 3.
The values of the coefficients for the function within the parenthesis are the following: ,
,
Take the value of b and divide it by 2. Then, the result obtained squares it.
Add and subtract
Write the expression of the form
The vertex is
Finding the equivalent angle of , the correct statements are given as follows:
Each angle on the second, third and fourth quadrants will have an equivalent on the first quadrant.
In this problem, the given angle is as follows:
It is on the third quadrant, as it is between pi and 1.5 pi, hence the equivalent on the first quadrant, also known as the reference angle, is given by:
The angle of 45º has equal sine and cosine, and tangent of 1, hence the correct statements are:
