In order to divide, you need to find the reciprocal of 4/15 and multiply it by 2/3. So, 2/3*15/4
The answer is 5/2
we are given

For finding inverse function , we do following steps
step-1:
Set f(x)=y

step-2:
Switch x and y

step-3:
now, we can solve for y

Multiply both sides by 9y-2



Add both sides by 2x


now, we can divide both sides by 9x

so, we get inverse function as

In order for the polynomial to be a degree of 4, it must have exactly 4 roots. According to the fundamental theorem of algebra: "The number of roots in a function is equivalent to the degree of the function"
These roots do not have to be real numbers, which means they can be imaginary or complex.
In this case, (-11 - √2i), (3 + 4i), and 10. There are three roots, which means that the polynomial can be a third of fourth degree polynomial. It is wrong for Patricia to assume that this is a fourth degree polynomial when only three roots are known.
<h3><u>The degree of the polynomial will at least be three, but could be higher.</u></h3>
