Answer: y = $\frac{1}{3}x - 3$

Step-by-step explanation:

We could find two points on graph to find the slope of the graph since we already know its y-intercept.The y-intercept is when x is 0.

We could find the points (0,-3) and another points ( 3,-2) to solve for the slope we will find the difference in y and divide it by the difference in the x values.

(0,-3)

(3,-2)

y -3 - (-2) = -1

x 0 - 3 = -3

-1/-3 = 1/3

so now we know the slope is 1 thirds or 1 over 3 and the y intercept is -3

so the equation will be y = 1/3x - 3

Answer:

x² + x + 1 + 2/(x - 1)

Step-by-step explanation:

(x³ + 1) / (x - 1) =
(x³ - 1 + 2) / (x - 1) =
(x³ - 1)/(x - 1) + 2/(x - 1) =
(x - 1)(x² + x + 1)/(x - 1) + 2/(x - 1) =
x² + x + 1 + 2/(x - 1)

Find f(x) if g(f(x))=x and g(x)=(x+1)/(x-1)

Firdavs [7]

Answer:

f(x) = (x +1)/(x -1)

Step-by-step explanation:

Let f(x) = y. We want to find y such that ...

g(y) = x

(y +1)/(y -1) = x

y +1 = xy -x . . . . . . multiply by y-1

y -xy = -x -1 . . . . . . add -1 -xy

y(x -1) = x +1 . . . . . . multiply by -1 and factor out y

y = (x +1)/(x -1) . . . . divide by the coefficient of y

Then ...

f(x) = (x +1)/(x -1)

_____

<em>Check</em>

g(f(x)) = ((x +1)/(x -1) +1)/((x +1)/(x -1) -1)

= ((x +1 +x -1)/(x -1)) / ((x +1 -x +1)/(x -1))

= 2x/2

= x

For the graph y = 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your an

MakcuM [25]

y = 1 is a horizontal line which has a slope of 0.
A line perpendicular to it, a vertical line, has an undefined slope. A line parallel to it, also a horizontal line, has a slope of 0.

Learn this, it helps..
HOY -- horizontal line, 0 slope, represented by y = a number
VUX -- vertical line, undefined slope, represented by x = a number.
