In each part below you will write two different MATLAB functions, poly$1$ and poly$2,$ to compute the nth$-$degree

polynomial,

$a_0+a_{1}x+a_2{x}^2+$dots$+a_n{x}^n$

Indicate each line you type below with the line number given in the comments.

a$)$ The function poly$1$ below will take two inputs a row vector, a$,$ containing the coefficients in the same order as above,

and a scalar real number, $x,$ which is the value at which the polynomial is to be evaluated. $($The function assumes $n1).$

The output, $y,$ will be the polynomial evaluated at $x.$ Use only the variables defined below to compute the sum, and no loops

The only built$-$in function you can use one needed to compute the sum. Fill in the blanks.

function $y=$poly$1(a,x)$

$q,m=$ length $(a)$
