Which of the following is the inverse of the function given below

ANSWER

EXPLANATION

The given function is:

Let

Interchange x and y.

Solve for y by first multiplying through by 7.

Add -2 to both sides of the equation.

Or

Hence the inverse function is:

the answer is vanilla

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
