<h3>Answer: True</h3>
Explanation:
Imagine that f(x) was a road without any gaps. The road can be straight or it can be curved somehow.
Now imagine that a horizontal line is the border between two countries. The country up north is the positive country and the southern country is negative.
f(1) > 0 means we're in the northern country since f(x) is positive here
then f(3) < 0 means we're now in the southern negative country
Somewhere along the road we must have crossed the border at least one time. This must be the case because the road does not have any gaps in it and we cannot teleport. This is what it means to be a continuous function. To draw a continuous curve, you cannot lift your pencil up.
So because f(x) transitions from positive to negative, this means f(x) = 0 at some point at least once. So that's why there exists a c such that f(c) = 0
Answer:
Step-by-step explanation:
Given that,
The diameter of the sphere, d = 6.4 cm
Radius, r = 3.2 cm
We need to find the volume of the sphere. The formula for the volume of a sphere is given by :
So, the volume of the sphere is equal to .
Answer:
15y^9
Step-by-step explanation:
Step 1: Multiply the coefficients
3 * 5
= 15
Step 2: Add the powers.
5 + 4
= 9
<em>Final answer: 15y^9</em>

Answer: Depends on the orders pairs
Step-by-step explanation: You didn’t include the ordered pairs so I’ll just do an example.
(1,5). (2,11). And(6,13) Theese orders pairs represent a function because, there are no repeating X values.
(2,5) (2,10) and (5,45)
Theese ordered pairs do NOT represent a function because, the X values repeat.
A function can be linear and nonlinear, they can have repeating Y values but NO repeating X values.
A trick for this is to put a piece of paper and cover sections and see if your line “turns back”.
Hope I helped ^u^
