Hello, 
To solve this function for f(4) we need to plug 4 into f(x) and the result will be our answer. We know that f(x) is 3x^2-7. Plugging in 4 we get 3(4)^2-7=41. Therefore, f(4)=41. Hope this helps!

What the question is asking you to do is plug in 4 in place of x in the given equation: 
f (x) = 3(4)^2-7 

4^2=16*3-17=41
Final answer: 41

What is theoretical vs practical domain in an exponential equation. Plz provide an example too
olya-2409 [2.1K]

Answer:

The theoretical probability of an event occurring is an "expected" probability based upon knowledge of the situation. It is the number of favorable outcomes to the number of possible outcomes. Example: ... There are 6 possible outcomes when rolling a die: 1, 2, 3, 4, 5, and 6. The only favorable outcome is rolling a 6.Practical domains and ranges narrow the solution sets to be realistic within defined parameters.The possible values of "x" is called the domain. The possible values of "y" is called the range.

What’s this guys ? I’ve been stuck on this ‍♀️
Harrizon [31]
SOLUTION:

Let's establish the formula for a cylinder as displayed below:

Let volume of cylinder = V

V = ( Pi )r^2h

Now let's substitute the values from the problem into the formula to find the volume.

V = ?

r = 8

h = 4

V = ( Pi )( 8 )^2( 4 )

V = ( Pi )( 64 )( 4 )

V = ( Pi )( 256 )

V = 256( Pi )

FINAL ANSWER:

Therefore, the answer is:

C. 256( Pi ) units^3

Hope this helps! :)
