Answer:

y = 150

Step-by-step explanation:

Proportions

It's given y is directly proportional to the square of x-1. It can be expressed as:

[tex]y=k(x-1)^2[/tex]

Where k is the constant of proportionality. We know y=24 when x=3. Substituting:

[tex]24=k(3-1)^2[/tex]

[tex]24=k(2)^2=4k[/tex]

Solving for k:

k = 24/4 = 6

Thus, the equation is:

[tex]y=6(x-1)^2[/tex]

When x=6:

[tex]y=6(6-1)^2=6(5)^2=6*25[/tex]

y = 150
