Answer:
The answers are in the box below. Check them out.
Step-by-step explanation:
if f(a) means when x = a, the value of f(a) would be the evaluated value.
[tex]f(6) = ...[/tex]
That means when x = 6, the value of y would be... As shown in the graph. The value of y is - 1 when x = 6.
[tex] \boxed {f(6) = -1}[/tex]
From the graph, when x = 2, y =-4. Therefore
[tex] \boxed {f(2) = - 4}[/tex]
The last problem. f(x) is defined as function f or function of x which equal to y-term.
[tex]f(x) = y[/tex]
Therefore when f(x)= -4 or y = - 4. The value of x would be
[tex]f(x) = - 4 \\ \boxed {x = 2,4,8, 10}[/tex]
Note that y = b where b is a constant will be a horizontal line graph. The line intercepts the graph of polynomial 4 points.
