Question

Consider this function.() = -31 + 3Which graph represents the inverse of function ?5XE3*-W.x3-12ZАwDZ

Answer 1

To know the inverse function, we have to change variables of the original function as follows:

$f(x)=y=-3x+3$$x=-3y+3$

Isolating for y:

$x+3y=3$$3y=3-x$

Thus, the inverse function is:

$y=-\frac{1}{3}x+1$

Based on the latter, we can see that the intersection with y -axis = 1, coordinate (0, 1). While the intersection with x - axis = 3, coordinate (3, 0)

Answer: C. Y
