Answer: 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.
