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
