Consider the ring Rix) of polynomials with real coefficients, with operations polynomial addition and polynomial multiplication (you don't have to prove this is a ring). For example, for the polynomials f(x)=1+2x+3x2 and g(x)=3-5x, we have f(x)+g(x)= (1+2x+3x2)+(3-5x)-4-3x+3x2 and f(x)g(x)(1+2x+3x2)(3-5x)=3+X-X2-15x). Show that the function h: RIX-R given by h(f(x)=f(0) is a ring homomorphism. Then describe the kernel ker(h).
