Answer:
non-linear, y = -6, x = 2 & x = 6, y = 2 & x = 4, above.
Step-by-step explanation:
The graph is not a straight line so that means that it is linear.
The y-intercept is the point at which the function touches the y-axis, which is at the coordinate point (0, -6), so y = -6.
The x-intercepts are the points at which the function touches the x-axis, which is at x = 2 and x = 6.
The highest y value is y = 2, and it happens when x =4.
Between x = 2 and x = 6, the function is above the x-axis line, so that means it must be above 0.
