The length of the fraser river is about 1370km, and the length of the columbia river is about 2000km. copy the statements below and fill in the blanks.
the columbia river is about what percent of the length of the fraser river.
step-by-step explanation: $31.64=$26.30+$0.21a
observation : graph is opening up, means end behaviour is same that is graph is ending in the same side .
so the graph must represent a even degree polynomial .
observation : graph is opening on the positive side of the y axis .
it means the leading coefficient of the polynomial must be positive .
so we are looking for the option which have even degree and the leading coefficient is positive . the correct option is b .
