If the coordinates of a function f(x) is defined as (x,y), then the coordinates of inverse of f(x) is defined as (y,x).

$f(g(y))=f(x)$ $[\because g(x)=(y,x)]$

$f(g(y))=y$ $[\because f(x)=(x,y)]$

If g(x) is the inverse of f(x), then the value of f(g(y)) is y.

It is given that g(x) is the inverse of f(x), then the value of f(g(2)) is 2.

Therefore third option is correct.

MARQUE UN PUNTO Y TRACE VARIAS RECTAS QUE PASEN POR EL.¿QUE CONCLUYE?

VladimirAG [237]

The generic equation of a line is:
y-yo = m (x-xo)
Where,
(xo, yo): It's an ordered pair either.
m: is the slope of the line.
We observe that for a point (xo, yo) infinite lines with different slope m can pass.
Answer:
The conclusion is that for the ordered pair (xo, yo) can pass infinite lines that satisfy:
y-yo = m (x-xo)

Find the x- and y intercepts for the linear equation

Vanyuwa [196]

4. 3x + 2y = 6

x-intercept = 2 , y - intercept = 3

5. 4x – 9y = 36

x-intercept = 9, y - intercept = -4

6. x + y = -3

x-intercept = -3, y - intercept = -3

8. x - 3y = 12

x-intercept = 12, y - intercept = -4
