x
is a straight line and is a curve, but both functions
are decreasing.
g (x) f (x)
is a straight line and is a curve, but both functions
are increasing.
g (x) f (x)
is a straight line and is a curve, but both functions
are decreasing.
f (x) g (x)
is a straight line and is a curve, but both functions
are increasing.
f (x)

Answer 1

f(x) = −3x + 2 is a straight line (slope −3 < 0) so it decreases.
g(x) = 3(1/2)^x is an exponential curve with base 1/2 < 1, so it also decreases.

So: f is a straight line and g is a curve, and both functions are decreasing.
