Answer 1

Answer to Q. No. a (1)

Intercepts

Intercepts are the ends where line intercets the x axis or y axis. There are two intercepts in a graph. An intercept where a line intersects x axis is known as x axis and a point where a line intersects y axis.

Answer to Q. No. a (2)

Downward sloping function

Function is a mathematical representation of a relation between two variables. If the relation between the variables is negative. i.e. both variables are moving in opposite direction it said to be a negative relation between the two variables.

Answer to Q. No. a (3)

Upward sloping function

Function is a mathematical representation of a relation between two variables. If the relation between the variables is positive. i.e. both variables are moving in same direction it said to be a positive relation between the two variables.

Answer to Q. No. b (1)

Polynomial function

It is a function which involves only positive integer exponents of a variable in an equation.
