To calculate: To write the given statements (a) and (b) as functions f(x) and g(x)respectively.
Professor Harsh gave a test to his college algebra class and nobody got more than 80 points (out of 100) on the test.
One problem worth 8 points had insufficient data, so nobody could solve that problem.

Calculation:
x represents the original score of a student.
10% of x is given by,
$\frac{10}{100}×x=0.1x$
So when the score is increased by 10%, the new score is given by,
x+0.1x = 1.1x
Therefore,
The function that represents the score increased by 10% is given by f(x) = 1.lx
When the original score is increased by 8 points,
The new score is given by,
x+8
Therefore,
The function that represents the score increased by 8 points is given by g(x) =x + 8.
