- (1)
Step-by-step explanation:
1.
[In the attachment]
2.
again taking 4 as x and 5 as y.
since,
y = f(x)
5 = f(4)
that is <u>option 3</u>.
3.
x = -3
y = -5
y = f(x) = -5
f(-3) = -5
<u>1st option</u>
4.
V(r) = 4/3 pi r³
here the ou.tput is V(r) when the input is r.
and since V(r) denotes volume of air inside the basketball
V(r) is the volume of basketball when the radius is r.
that is option 2.
5.
given that:-
x = 9, f(x) = 5
•°• f(9) = 5
that is the <u>1st option</u>

Answer:
and
in interval notation.
Step-by-step explanation:
We have been given a compound inequality . We are supposed to find the solution of our given inequality.
First of all, we will solve both inequalities separately, then we will combine both solution merging overlapping intervals.
Dividing by negative number, flip the inequality sign:
Dividing by negative number, flip the inequality sign:
Upon merging both intervals, we will get:
Therefore, the solution for our given inequality would be and
in interval notation.
