You need to plot a function, but how to do this?

Question

Mathematics

First graph of the function:
Domain of definition: -4; 6
Multiple values: -2; 1
Intersection points of function graphs with OX axis and OY axis: (-4; 0), (0; 6)
Intervals:
-increase [-4; -2] and [4; 6]
-decreasing [-2; 4]
Maximum points -2
Maximum of function f(-2)=1
Minimum points 4
Minimum points of function f(0)=0
Additional points: f(0)=0
