For the graph below, what should the domain be so that the function is at least 300?

graph of y equals minus 2 times the square of x plus 50 times x plus 300

x _ 0

-5 _ x _ 30

0 _ x _ 25

all real numbers

The domain of the function so that the function is at least 300 is:

0 ≤ x ≤ 25

Step-by-step explanation:

We are given graph of the function y as:

on subtracting both side of the inequality by 300 we obtain:

This inequality is obtained when one of the term is positive and the other is negative:

i.e. if x≥0

and x-25≤0

i.e. x≤25 then the product :

-2x(x-25)≥0.

Hence, the domain is:

  0 ≤ x ≤ 25

y=1/4x-4
