Answer:

Follows are the solution to these questions:

Step-by-step explanation:

For point a:

Let the number is = x then,

equation / mapping function:

[tex]\to (x+22.5) \times 2=y\\\\[/tex]

For point b:

Calculating the inverse function:

[tex]\to x = \frac{y}{2} -22.5\\\\[/tex]

now we change the value of x and y so, it will gives the inverse function in standard parameters:

[tex]\to y = \frac{x}{2} -22.5\\\\[/tex]
