Answer:
Graph (2)
Step-by-step explanation:
We have to find the graph that represents the solutions of the quadratic equation as x = -4 and x = 2
Graph which has x-intercepts as x = 2 and x = -4 will be the answer.
Graph (1)
x-intercepts in this graph are x = -2 and x = 4
Not the answer.
Graph (2)
x-intercepts in this graph are x = -4 and x = 2
This option will be the answer.
Graph (3)
Only one x-intercept has been given in this graph
Not the answer.
Graph (4)
x-intercepts are x = -5 and x = -3
Not the answer.
