I need to know if there functions or not (algebra)
faust18 [17]

Answer:

Number 14 is a function and Number 16 is NOT a function.

Step-by-step explanation:

To check if a set of numbers form a function, you can look at the x values or the imput values.

For number 14 the x values are : 4,-3,-4,5,6. When looking at these values, there can only be one of each number.

For example in number 16, there's two 0's and we cannot allow that! So therefore, number 16 is not a function.

Also note, the y values are called the outputs.

A function is only allowed to have ONE imput with each output.

Hope this helps! :)

Steve kicks a football into the air. The path that a ball takes can be described by the equation h=20t - 5t squared where h is t
FinnZ [79.3K]
Since h represents the height of the ball at any given time, t, let h = 25, such that the ball will be 25m high at t.

Now, we have 25 = 20t - 5t²
5t² - 20t + 25 = 0
t² - 4t + 5 = 0

\frac{4 +- \sqrt{16 - 20}}{2}

Since the discriminant is less than zero, there are no solutions.
Hence, the ball will never be 25m high.

Can relative maximums and minimums be at the endpoints? I know global max/min can be at endpoints but I'm not sure about relativ
KatRina [158]

Answer:

No

Step-by-step explanation:

Just because the derivative is 0 at a point doesn't necessarily mean it is a relative minimum or maximum.  You must be able to evaluate the derivative on both sides of the point to determine if it changes signs.  Since endpoints have only one side, they cannot be relative maximums or minimums.
