If f(x) = 3x 2 + 1 find f(6).

f(6) = 109

Step-by-step explanation:

If f(x) = 3x 2 + 1 we replace x with 6 in the given function

f(6) = 3×6^2 + 1 first find the second power of 6

6^2 = 36 then multiply it by 3

36 × 3 = 108 and then add 1

108 + 1 = 109

To find the number of seats, let's do it using multiplication!

First, to see how many seats are in one big section of the theatre, multiply 7 groups of seats by 25 seats:

7 x 25 = 175

Now, knowing this, multiply 175 by 4 to get the total number of seats in the theater!

175 x 4 = 700

Therefore, there are 700 seats in the theatre.

Hope this helps!
