Step-by-step explanation:
[tex]f(x) = {2}^{(x - 5)} [/tex]
[tex]f(8) = {2}^{(8 - 5)} [/tex]
[tex]f(8) = {2}^{3} [/tex]
[tex]f(8) = 8[/tex]
Answer:
Answer: Third objective
Step-by-step explanation:
[tex]{ \tt{f(x) = {2}^{(x - 5)} }}[/tex]
when x is 8, f(x) is f(8):
[tex]\dashrightarrow \: { \tt{f(8) = {2}^{(8 - 5)} }} \\ \\ { \tt{f(8) = {2}^{3} }} \\ \\ { \tt{f(8) = 2 \times 2 \times 2}} \\ \\ \dashrightarrow \: { \boxed{ \tt{f(8) = 8}}}[/tex]
