For the graph, what is a reasonable constraint so that the function is at least 200?

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one

For the graph below, what should the domain be so that the function is at least 200?   graph of y equals minus 2 times the square of x plus 30 times x plus 200

My

Given the above information, we have:

To make  the function is at least 200, it means that:

≥ 200

<=> ≥ 0

<=> x(-2x+30) ≥ 0

This is the product of two numbers hence would be positive only if either both are positive or both are negative

x ≥ 0 and  (-2x+30) ≥ 0

<=> 0 ≤ x ≤ 15

Then we get

This is inconsistent as a value cannot be less than 0 and greater than 15

=> our correct answer is

Hope it will find you well.

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
