Answer
False statement
Work Step by Step
The equation of any linear function is $f\left( x \right)=mx+b$, and the graph of the linear function is a straight line.
Also, the equation of any quadratic function is $f\left( x \right)=a{{x}^{2}}+bx+c$, and the graph of a quadratic equation is parabolic.
Thus, the statement is false.
