Function A: Non-Linear

Function B: Linear

Step-by-step explanation:

[Function A] We can tell if it is linear by graphing the given points. See attached. Since we cannot graph a straight line that goes through all of the points, it is non-linear.

[Function B] This function is linear as every input has only one output, and it is a straight line with a constant slope.

Have a nice day!

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
