Brent could represent a rectangle with the dimensions of x - 1 and x - 6, then demonstrate that the area equals the combination of x^2, -x, -6x, and 6.
Answer:
Option (a) is the correct choice.
The result of the given function
at x = 3 is -28
Detailed explanation:
Provided: Function 
We need to calculate the function's value at x = 3
Evaluate the specified function 
As we are required to find the function's value at x = 3
Substitute x = 3 into the function f(x)

Upon simplification, we get

Thus, the value of the given function
at x = 3 is -28
Given that the relationship is linear.
The equation can be expressed as y = mx + c.
Substituting, when x = 0, we have y = 32.
Thus, 32 = c.......( 1 )
Then, when x = 100, y results in 212.
Which gives us:
212 = 100m + c.......( 2 )
By equating equations 1 and 2, we obtain:
100m = 212 - 32
Solving for x yields 1.8.
The final equation is therefore y = 1.8x + 32.
Hence, this represents the required solution.
