Hey there!!
Fill in the blanks :-
⇒ First graph the line. Locate the value of x on the x-axis. Draw a vertical line from point plotted on the x-axis to the graph of the function and a horizontal line segment from the graph of the function to the y-axis.
Find the value of f(x) when x is -2.
Remember :- f(x) is basically the y-value. It is just denoted as _f(x), it stands for function of x. Which means, the value of y, depends upon the value of x or the function of x.
Given : x = - 2
Plugging in the values :
...
...
...
The last fill in the blank :
The value of y on the y-axis is the value of the function. Therefore, the value of f(x) is -7 when x is -2.
Hope it helps!!
