Answer:
Linear function: straight line
absolute value function: V-shaped
Quadratic function: U shaped
Constant function: horizontal line
Step-by-step explanation:
A linear function is a straight line when represented on a graph.
A constant function has a slope of zero. Thus, when it is plotted on the graph, the line is horizontal.
When we plot a quadratic function on a graph, the result is a parabola. A parabola has a curved shape
When we plot an absolute value function on a graph, the result would be two straight lines forming a v shape.
