What are the x-intercepts of the graph pf the function below? y=x^2+3x=28

 The required x-intercepts are (4, 0) and (-7, 0).

Step-by-step explanation:  We are given to find the x-intercepts for the parabola defined by the following equation :

We know that

the x-intercepts of a function are the points where the y co-ordinate is zero.

So, from equation (i), we have

Therefore, the x-intercepts of the given function are (4, 0) and (-7, 0).

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000
