Answer:
x is greater than or equal to -7 but less than 9.
Step-by-step explanation:
Find the lowest and higest points on the graph.
Remember the domain is on the x - axis.
The lowest point on the graph is -7, but the dot is filled in so it must be equal to it.
The next step is that the graph is getting larger so it is greater than or equal to.
On the other side of the graph do the same but it is less than not equal because the dot is open.
Answer:
see explanation
Step-by-step explanation:
Given
(x + 2)(x - 7) = 0 ← in standard form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 7 = 0 ⇒ x = 7
Thus the zeros are x = - 2 and x = 7
This expression is a difference of squares:
