Question

Exponential function? And Common ratio :And Function : Pls help me with question 1

Answer 1

Given the question in the image, the following are solution steps to answer the question

STEP 1: Define Exponential function

An exponential function is a mathematical function of the following form:

`y=a^x`

where x is a variable, and a is a constant called the base of the function.

STEP 2: Check if the table in question 1 is an exponential function

`\begin{gathered} y=a^x \\ \text{For first row,}y=3,x=1 \\ 3=a^1,a=3 \\ \text{For second row,} \\ y=\text{ }a^x \\ \text{when }x=2 \\ y=3^2=9 \\ y=6\text{ in the table} \\ 6\\e9 \\ \text{Hence, the table is not an exponential function} \end{gathered}`

Hence, the table in question 1 is not an exponential function, has no common ratio and has no specific exponential function.
