Answer:
The missing expression is 'b'.
Step-by-step explanation:
We have been given an incomplete sentence. We are supposed to fill in the given blank.
Sentence:
The value of the _____ determines whether the graph of an exponential function increases or decreases from left to right.
We know that an exponential function is in form [tex]y=a\cdot b^x[/tex], where,
a = Initial value,
b = For growth [tex]b>1[/tex] and for decay [tex]b<1[/tex].
Therefore, the value of 'b' determines whether the graph of an exponential function increases or decreases from left to right.
