Question

3) Use the graph to determine if the associated function would have a POSITIVEor NEGATIVE leading coefficient.N-1-3O positivenegativeO cannot be determined

Answer 1

it is an exponential function, of the form:

`\begin{gathered} f(x)=ax^k+bx^(k-1)+\cdots+ck^(k-n) \\ \text{where:} \\ k=2m,m\in N \end{gathered}`

since it opens upward:

`a>0`

Therefore, the coefficient is positive
