Will mark brainliest! part a: a graph passes through the points (0, 4), (1, 8), and (2, 10). does this graph represent a linear function or a non-linear function? explain your answer in words. part b: write one example of a linear function and one example of a non-linear function. (use x and y as the variables)

part a :yes it is a linear function because it is a straighten lined   Part b : LINEAR FUNCTION  Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x. When x is 0, y is already 1. NONLINEAR FUNCTION  An example of a nonlinear function is y = x^2. This is nonlinear because, although it is a polynomial, its highest exponent is 2, not 1.

Step-by-step explanation:

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
