What are the x-intercepts of the graph of the function below?

Option B (-7,0) and (4,0) is the correct answer.

Step-by-step explanation: It is requied to find the x intercept of the equation y = x^2 + 3x -28.

X Intercept is the point at which the line cuts the x axis. To find the x intercepts of the given equation we have to put y = 0

So, x^2 + 3x -28 = 0

On solving this we will get the values of x as 4 and -7.

So there are two x intercepts for the given equation (4,0) and (-7,0)

Hope it helps.

Thank you :)

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
