What can you say about thedirection of the force acting on the book? The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book. Since these two forces are of equal magnitude and in opposite directions, they balance each other. The book is said to be at equilibrium.
* Define a Linear function. b. Quadratic function. c. Polynomial function. Answer: Linear function : are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. Quadratic function : is a function that can be described by an equation of the form fx = ax2 + bx + c, where a ≠ 0. In a quadratic function, the greatest power of the variable is 2. The graph of a quadratic function is a par Polynomial function : has the form , where are real numbers and n is a nonnegative integer. In other words, a polynomial is the sum of one or more monomials with real coefficients and nonnegative integer exponents. The degree of the polynomial function is the highest value for n where an is not equal to 0.
