Mathematics

Since $q(\frac{3}{4}) \neq 0$ , 3/4 cannot be a root of q(x).

Step-by-step explanation:

Root of a function:

If $x^{\ast}$ is a root of a function f(x), we have that $f(x^{\ast}) = 0$ .

In this question.

We have to find $q(\frac{3}{4})$ . So

$q(\frac{3}{4}) = 6(\frac{3}{4})^3 + 19(\frac{3}{4})^2 - 15(\frac{3}{4}) - 28$

$q(\frac{3}{4}) = \frac{162}{64} + \frac{171}{16} - \frac{45}{4} - 28$

$q(\frac{3}{4}) = \frac{162}{64} + \frac{684}{64} - \frac{720}{64} - \frac{1792}{64}$

$q(\frac{3}{4}) \neq 0$

Since $q(\frac{3}{4}) \neq 0$ , 3/4 cannot be a root of q(x).
