Option A) Circle.
Step-by-step explanation:
We are given the equation:
A general equation of the circle is of the form:
where (h,k) is the center of the circle and r is the radius of circle.
Comparing the two equations, we get,
Thus, the given equation is equation of a circle centered at (3,12) and of radius 5 units.
Answer:
An even function is:
f(x) = 7
Step-by-step explanation:
An even function accomplish the following condition:
f(x)=f(-x) (1)
Applying (1), we have:
- f(x)= (x-1)^2
f(-x)
- f(x)= 8x
- f(x)= x^2 -x
- f(x)=7 = f(-x)= 7
The last one is even.
