Answer:
Step-by-step explanation:
Given the quadratic equation as:
Let us put 
for simplicity of the equation:
Now, the equation becomes:
Now, let us try to solve the quadratic equation:
So, the solution to the given trigonometric quadratic equation is:
and
Let us try to find the values of 
in the interval 
.
can have a value equal to 
in 1st and 2nd quadrant.
So, can be
For ,
So, the answer is:
Answer:
Options (1), (3) and (7)
Step-by-step explanation:
Characteristics of the given graph are as followed.
1). For every input value (x-value) there is a different output values (y-values).
So the points on the graph represent a function.
2). Coordinates of all the points are distinct and separate (not in fractions or decimals).
Function given is a discrete function.
3). For every increase in the x-values of the points there is a decrease in y-values.
Therefore, given function is a decreasing function.
Therefore, Options (1), (3) and (7) are the correct options.
Answer:
I need the function and graph to be able to answer this
