Which function is increasing?

B.) f(x) = 4^x

Step-by-step explanation:

In mathematics, an exponential function is a function of the form f(x) = b^x where b is a positive real number not equal to 1, and the argument x occurs as an exponent.

∠cbe and ∠deb are same-side interior angles.

i took the test

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:
