Given:
To find:
The domain of the given function.
Solution:
Domain is the set of input values or x-values.
In the given function, the x-coordinates of ordered pairs are 3, 6, -1, 5 and -4. So, domain is the set of these values in ascending order.
The set builder form of domain is
Therefore, the correct option is C.
We want to find the axis of symmetry of the function;
STEP 1:
The equation for the axis of symmetry of a line is given as;
From the equation, a = 6 and b = -3, so,
STEP 2: Insert the values of a and b into the equation to obtain;
CONCLUSION:
Therefore, we see that the axis of symmetry is the line;
