Answer:
f(10) means to input x = 10 into the function.
From inspection of the given function:

the "10" is the numerator of the fraction.
Therefore, swap the "10" for "x" to give the function in terms of x:

[1], [3] => a = 49,000/2 = 24,500 => b +c = 24,500 => c = 24,500 - b;
[2] => 25*24,500 + 20b + 15c = 1,052,000 => 20b + 15c = 1,027,500;
20b + 15*(24,500 - b) = 1,027,500 => 5b = 733,500 => b = 146,700 =>
c = - 122,200;
Answer:
