both Qs pls using matlab

A very important function in engineering applications is the Bessel function of the first kind. The Bessel function of the first kind of order 0, denoted by J_0(x), is represented in MATLAB by bessel j(0, x). The zeros of Bessel functions arise in applications such as vibration analysis of circular membranes. Find the first four positive zeros of J_0(x), and verify them graphically. Find the first four positive zeros of the Bessel function of the first kind of order 1, denoted by J_1(x), represented in MATLAB by bessel j(1, x), and verify them graphically
