Lenox ironed 1/4 of the shirts over the weekend. She plans to split the remainder of the work equally over the next 5 evenings.

MrMuchimi

3/20, or 0.15 of the shirts each evening

1 - 1/4 = 3/4

(3/4) / 5 = (3/4) / (5/1) = (3/4) x (1/5) = 3/20 = 0.15

The table below shows some inputs and outputs of the invertible function f with domain all real numbers.

Ratling [72]

Answer:

${f}^{ - 1} (f(93)) = 93$

$f(f(7)) = - 15$

Step-by-step explanation:

A function and its inverse has the following properties

${f}^{ - 1} (f(x)) = x$

This implies that;

${f}^{ - 1} (f(93)) = 93$

From the table,

$f(7) = - 6$

This means that:

$f(f(7)) = f( - 6)$

$f(f(7)) = - 15$

Note that: f(7) means the value of f(x) when x=7.

From the table f(x)=-6 when x=7.

That is why f(7)=-6.
