What is the coordinate a and b please

The coordinates are:

A (-2.5, -1.5)

B (4.5, -3.5)

Step-by-step explanation:

A coordinate is a point on a graph that is a representation of the numbers on the x and y axes, if a line is drawn from that point to the various axes.

For example the coordinate of a point c on a graph is written as C (x,y)

from the graph at point A, if a line is drawn from that point to touch that x and y axes, it will touch x axis at -2.5 (between -2 and -3) and y axis at -1.5 ( between -1 and -2), while the point B will touch the x axis at 4.5 (between 4 and 5) and the y axis at -3.5 (between -3 and -4). hence the coordinates of A and B are (-2.5, -1.5) and (4.5, -3.5) respectively.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
