How could you describe the graph of

 $f\left(x\right)=75\left(\frac{1}{4}\right)^x$  ?

• The graph has an initial value of 75 and each successive term is found by subtracting ¼. 

• The graph has an initial value of 18.75 and each successive term is found by multiplying by ¼.

• The graph has an initial value of 18.75 and each successive term is found by dividing by 4.

• The graph has an initial value of 75 and each successive term is found by multiplying by ¼.
