10.1 inverses of simple quadratic and cubic functions

Answers

Answer 1

The inverse function of the cubic function is its opposite

The inverse function of [tex]f(x) = 5x^3[/tex] is [tex]f^{-1}(x) = \sqrt[3]{\frac x5}[/tex]

How to determine the inverse of the function?

The cubic function is given as:

[tex]f(x) = 5x^3[/tex]

Express f(x) as y

[tex]y = 5x^3[/tex]

Swap the positions of x and y

[tex]x = 5y^3[/tex]

Divide both sides by 5

[tex]y^3 = \frac x5[/tex]

Take the cube roots of both  sides

[tex]y = \sqrt[3]{\frac x5}[/tex]

Express y as an inverse function

[tex]f^{-1}(x) = \sqrt[3]{\frac x5}[/tex]

Hence, the inverse function of [tex]f(x) = 5x^3[/tex] is [tex]f^{-1}(x) = \sqrt[3]{\frac x5}[/tex]

Find the output, bbb, when the input, aaa, is 666. b = -1-7ab=−1−7a

Answers

The output of the given algebra b = -1 - 7a with the given input of a = 6 is calculated to be; b = -43

How to solve basic algebra?

We are given the algebra;

b = -1 - 7a

where;

a is the input

b is the output

Now, we are given the value of the input to be a = 6

Thus, output is calculated as;

b = -1 - 7(6)

b = -1 - 42

b = -43

Thus, the output of the given algebra with the given input is -43.
