For which pairs of functions is (f•g)(x) = x? O Rx) = x? and (x)=
1
X
and g(x)
2
X
o Rx)= a
o f(x)= *52 and g(x) = 2-3*
o Rx)= {x-2 and g(x) = x+ 2

25% is the answer

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
