The table below shows some inputs and outputs of the invertible function fff with domain all real numbers.
kherson [118]

Answer:

f^{-1}(-2) = 3

f^{-1}(-1) = 18

Step-by-step explanation:

Table

x      | 5    | 3    | 1     | 18   | 0    | 9

f(x)   | 9    | -2   | -5   | -1    | 1     | 11

We are asked ti find the following values:  f^{-1} (-2) and f^{-1} (-1)

f^{-1}(x) is the inverse of f(x).

In the same way that given some x value you obtain f(x), if you have an f^{-1}(x) value, you obtain x values

Part A The measure of ∠AFC is 120°, and the measure of ∠BFC is 95°. Which equation can you use to find the measure of ∠AFB? 120°
aev [14]

Answer:

x = 120-95

Step-by-step explanation:

The correct equation for the expression is:

∠AFC = ∠AFB+ ∠BFC

Given that

∠AFC = 120°

∠BFC = 95°

Substitute

120= ∠AFB+95

∠AFB = 120-95

If ∠AFB = x

The required equation will be:

x = 120-95
