Question

State whether the graph of f(x)=(x^3+15x^2+56x)/7 has infinite discontinuity, jump discontinuity, point discontinuity, or is continuous.

Answer 1

\[f(x)=\frac{ x^3+15x^2+56x }{ 7 }\]

Answer 2

continuous: this is a polynomial-- no variable in the denominator, and all whole number exponents (no matter what number you plug in for x, you'll get a real answer for f(x))

Answer 3

That's what I thought :) Thank you

Answer 4

no problem :)
