please answer fast only MCQ no need for justifcation MATLAb

Consider the polynomials q(x) = 2x3 - X + 7 and r(x) = x2 + 3x. 1. To plot the function qx) over (10,20] we use: a. q=sym(2*x^3-x+7) ezplot(q.[10 201 b. fplot(2*x^3-x+7'.[10 201 c. 9=[2 0 -1 7] x=10:0.1:20: y=polyval(p.x): plot(x,y) d. None of the above 2. To calculate r(2), we use: a. r=inline(*x^2+3x) r(2) b. =[1 3 0] polyval(r.2) c. syms x: =x^2+3x subs(f.x.2) d. all the above
