Answer:
The answers are in the box below. Check them out.
Explanation:
if f(a) means when x = a, the value of f(a) would be the evaluated value.
![f(6) = ...](https://img.qammunity.org/2022/formulas/mathematics/high-school/4gtiq0hqcdch2yowz7znuqnygvw1i8jnyc.png)
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.
![\boxed {f(6) = -1}](https://img.qammunity.org/2022/formulas/mathematics/high-school/jltc8xopaveqr1j42pnx8x47h3ptfkwri2.png)
From the graph, when x = 2, y =-4. Therefore
![\boxed {f(2) = - 4}](https://img.qammunity.org/2022/formulas/mathematics/high-school/49lhzpvmb9qwylbx1yss2qwz84tzpyp9ao.png)
The last problem. f(x) is defined as function f or function of x which equal to y-term.
![f(x) = y](https://img.qammunity.org/2022/formulas/mathematics/high-school/i8hordmtbl92iz0ocmfu7e857t4xwnq1hw.png)
Therefore when f(x)= -4 or y = - 4. The value of x would be
![f(x) = - 4 \\ \boxed {x = 2,4,8, 10}](https://img.qammunity.org/2022/formulas/mathematics/high-school/taxcawagbi3ocddcvypn145gqeuxk3i74e.png)
Note that y = b where b is a constant will be a horizontal line graph. The line intercepts the graph of polynomial 4 points.
