Step-by-step explanation:
The given function is :
(a) To find f(9), put x = 9 in the above expression.
(b) To find f(x+7), put x = x+7 in the above expression.
(c) To find f(-x), put x = -x in the above expression.
Hence, this is the required solution.
The discontinuity are the point wherein the function is not defined.
The zeros are the points wherein f(x)=0.
Computing the discontinuity points:
Set
then the discontinuity point is at
.
Comptine the zeroes:
Set
Compute the discriminant:
Then with quadratic formula we get the solutions:
The two zeros are
Answer:
<u>It would cost about $2.90</u>
Step-by-step explanation:
<em>You have to first see how much inches are in a foot and divide that by how much it costs.</em>
