Class 9th math Review Exercise 3 solution english PCTB

Question 10: If \(g(x)=7x-2\) and \(s(x)=8x^2-3\) find:

\((iii)\) \(\;\) \(g(-\frac{5}{3}) \)

Solution:

\(g(x)=7x-2\)

\(g(-\frac{5}{3})=7(-\frac{5}{3})-2\)

\(\ \ \ \ \ \ \ \ \ \ \ =-\frac{35}{3}-2\)

\(\ \ \ \ \ \ \ \ \ \ \ =\frac{-35-6}{3}\)

\(\ \ \ \ \ \ \ \ \ \ \ =-\frac{41}{3}\)
