Answer:

The percentage of error is 14.71 %.

Step-by-step explanation:

Given:

Estimated time for completion of project is, ET=17\ h

Actual time for completion of project is, AT=19\frac{1}{2}=\frac{39}{2}\ h

Difference in error =AT - ET = \frac{39}{2}-17=\frac{39-34}{2}=\frac{5}{2}=2.5\ h

Percentage in error = \frac{2.5}{17}\times 100=14.71\%

Therefore, the percentage of error is 14.71 %

Let the function be represented by f(x).

Multiplying the number x by 4 results in 4x. Subtracting 2 from results give 4x - 2. So the function becomes:

f(x) = 4x - 2

Finding the inverse function:

Replace f(x) by y, and isolate x on one side of the equation and find the inverse:

y = 4x - 2\\\\ y + 2 = 4x\\\\ x = \frac{1}{4}(y + 2)\\     \\  f^{-1}(y)=\frac{1}{4}(y + 2)\\     \\  f^{-1}(x)=\frac{1}{4}(x + 2)

Yes the inverse function represents the reverse process. Original function involved multiplication by 4 and then subtraction of 2. Inverse function involves addition of 2 and then division by 4. So the inverse represents the reverse of the given process.
