What is the inverse of g? <br> g(x) = 3/x+7

ikadub [295]

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) .

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

A population of 30 swans halves every 10yr. Which graph represents the population growth?

Anton [14]

Answer:

The second graph

Step-by-step explanation:

If the population halves every 10 years, the population at year 10 would be half as mush as year 0, and year 20 would have half as much as year 20, and so on, graph 2 is the only one with a decreasing slope.

V = 128 – 32t

tamaranim1 [39]

Answer: The Y intercept is 128 as well, which is the original velocity. Technically it should be v - intercept but whatever. The y / v intercept is the original velocity. The X intercept should be the t intercept but again whatever. The x/t intercept is 4, meaning that the velocity is zero when t is 4

Step-by-step explanation: y/v intercept is when t = 0. v = 128 - 32(0) = 128

It is the initial velocity at t = 0. The X/t intercept is when v = 0. 0 = 128 - 32t, so 32t = 128, so t = 4. The x intercept means when the velocity is zero, which means that the ball is at its highest/farthest point.
