What is the y-intercept of f–1(x)?

wolverine [178]

Answer:

-16

Step-by-step explanation:

The given linear function is ; $f(x)=\frac{3}{4}x+12$

Let $y=\frac{3}{4}x+12$ .

We interchange x and y.

$x=\frac{3}{4}y+12$ .

We solve for y.

$x-12=\frac{3}{4}y$ .

We now multiply through by $\frac{4}{3}$ to get:

$\frac{4}{3}x-12\times\frac{4}{3}=y$ .

This simplifies to;

$y=\frac{4}{3}x-16$ .

Hence $f^{-1}(x)=\frac{4}{3}x-16$ .

The y-intercept is -16

Can someone please help me with this question?!?

Answer:

(3, 10, 17, 24....)

Step-by-step explanation:

f(x) = 7x - 4

x = 1:

f(1) = 7*1 - 4 = 7 - 4 = 3

x = 2:

f(2) = 7*2 - 4 = 14 - 4 = 10

x = 3

f(3) = 7*3 - 4 = 21 - 4 = 17

then the sequence is:

(3, 10, 17, 24.....)
