Hello!
Tangent lines have only one point on the circle, meaning they form straight angles with the edge of the circle. The radius goes from the center of the circle to the point where the tangent line is on circle, creating a right angle.
Answer:

Hmmmm not sure
Explanation: I took this test and got it correct
Answer:
Step-by-step explanation:
Given is a function f(x)

We have to analyse and sketch the graph
X intercept : Put y =0, we get x=0
Y intercept: Put x =0 , we get y =0
No exception for x or y and hence set of all real numbers is domain and range.

f' becomes 0 not at finite points
So relative extreme
Graph is sketched and attached
