Which set of ordered pairs could be generated by an exponential function?
olasank [31]

Answer:

The correct option is  (1,2), (0, 1), (1, 2), (2, 4).

Step-by-step explanation:

Consider the provided ordered pairs.

The exponential function is in the form of f(x)=ab^x

Where,  a is the initial amount a\neq 0 and  b is the rate of change b>0, b\neq 1

The graph of each exponential function passes through the point (0, a),

f(0)=a\cdot b^0 = a and a\neq 0  

Therefore, Option 1 and 2 and 4 are false.

Hence, the correct option is  (1,2), (0, 1), (1, 2), (2, 4).
