I a function is even the leading term will have an even exponent. If a function is odd than the leading terms exponent is odd.
an even function has a parabola looking graph, while an odd function has min and max graph
Complete the equation of variation where y varies inversely as x and y = 0.125
when x=8
There are 4 terms.
The second term and the fourth term have negative coefficients.
Terms are only negative depending on the value of the variables.
