Question

Which ordered pairs lie on the graph of the exponential function f(x)=3(1/4)^x ? Select each correct answer.

Answer 1

Answer:

Options 1 and 2

Explanation:

We nee to check which points are satisfying the given function $f(x)=3(\frac{1}{4})^x$

In case 1 we will pu x= -2 in given function we will get $\frac{3}{1/16}$=48

Hence, option 1 is correct

In case 2 we will put x=0 in given function we will get $3(\frac{1}{4})^0=3$

Hence, option 2 is correct

In case 3 we will put x=2 in given function we will get $3(\frac{1}{4})^2= \frac{3}{16}$

Hence, not satisfying the function so incorrect

In case 4 we will put x=12 in given function we will get $3(\frac{1}{4}})^{12}$$=3(\frac{1}{16777216})\neq0$

Hence, not satisfying the function so incorrect.
