\( 1 \frac{3}{2} \leqslant x<5 / 2 \) et \( \frac{2}{3} \leqslant y \leqslant \frac{4}{3} \) exarder \( x+y, x-y, x+y, \frac{x-3 y}{x} \)

\( 8 x y \) is a monomial expression. Is the statement true or fause?

O Functions and Lines Evaluating functions: Linear and quadratic or cubic The functions \( f \) and \( g \) are defined as follows. \[ f(x)=-2 x^{2}-3 \quad g(x)=3 x-1 \] Find \( f(5) \) and \( g(-2) \). Simplify your answers as much as possible. \[ f(5)=\square \] \( g(-2)=\square \)

Evaluating functions: Linear and quadratic or cubic The functions \( f \) and \( g \) are defined as follows. \( f(x)=3 x^{3}+5 \quad g(x)=-5 x+4 \) Find \( f(-2) \) and \( g(7) \). \[ f(-2)=\square \] \( g(7)=\square \)
