Mathematics

ikadub [295]2 years ago
6 0

Given function :-

\bf \implies g(x) = \dfrac{3}{x}+7

  • To find its reverse , substitute y = g(x) .

\bf \implies y = \dfrac{3}{x}+7

  • Interchange x and y .

\bf \implies x = \dfrac{3}{y}+7

  • Solve for y .

\bf\implies \dfrac{3}{y}= x -7 \\\\\bf\implies y =\dfrac{3}{x-7}

  • Replace y with f-¹(x) .

\implies\boxed{\red{\bf f^{-1}(x) = \dfrac{3}{x-7} }}

30 points!<br> You start at (-2, 2). You move left 3 units and right 10 units. Where do you end?
Cerrena [4.2K]

Answer:

The answer is (5, 2)

Step-by-step explanation:

I. If move left = -x

    move right = +x

  So -2 - 3 =  -5 => move left

        -5 + 10 = 5 => move right

I suggest that move left and right is x cordinate

The answer is (5,2)

Is that correct?
