Studdy Solution

STEP 1

1. The function f(x) f(x) is defined piecewise with different expressions for x<6 x < 6 and x6 x \geq 6 .
2. We need to evaluate f(x) f(x) at specific values x=4,5,6,7,8 x = 4, 5, 6, 7, 8 and fill in the corresponding f(x) f(x) values in the table.

STEP 2

1. Evaluate f(x) f(x) for x=4 x = 4 .
2. Evaluate f(x) f(x) for x=5 x = 5 .
3. Evaluate f(x) f(x) for x=6 x = 6 .
4. Evaluate f(x) f(x) for x=7 x = 7 .
5. Evaluate f(x) f(x) for x=8 x = 8 .

STEP 3

Evaluate f(x) f(x) for x=4 x = 4 .
Since x=4<6 x = 4 < 6 , use the expression f(x)=36x2 f(x) = 36 - x^2 .
f(4)=3642=3616=20 f(4) = 36 - 4^2 = 36 - 16 = 20

STEP 4

Evaluate f(x) f(x) for x=5 x = 5 .
Since x=5<6 x = 5 < 6 , use the expression f(x)=36x2 f(x) = 36 - x^2 .
f(5)=3652=3625=11 f(5) = 36 - 5^2 = 36 - 25 = 11

STEP 5

Evaluate f(x) f(x) for x=6 x = 6 .
Since x=66 x = 6 \geq 6 , use the expression f(x)=x6 f(x) = x - 6 .
f(6)=66=0 f(6) = 6 - 6 = 0

STEP 6

Evaluate f(x) f(x) for x=7 x = 7 .
Since x=76 x = 7 \geq 6 , use the expression f(x)=x6 f(x) = x - 6 .
f(7)=76=1 f(7) = 7 - 6 = 1

STEP 7

Evaluate f(x) f(x) for x=8 x = 8 .
Since x=86 x = 8 \geq 6 , use the expression f(x)=x6 f(x) = x - 6 .
f(8)=86=2 f(8) = 8 - 6 = 2
The completed table is:
\begin{tabular}{|l|l|l|l|l|l|} \hline x & 4 & 5 & 6 & 7 & 8 \\ \hline f(x) & 20 & 11 & 0 & 1 & 2 \\ \hline \end{tabular}
