Evaluate the function for the given value.f(t) = t²− t − 2; t = 9

Sagot :

Answer:

f(9)=70

Explanation:

Given f(t) below;

[tex]f\mleft(t\mright)=t^2-t-2[/tex]

To evaluate the function at t=9, substitute 9 for t in f(t).

[tex]f(9)=9^2-9-2[/tex]

After the substitution, then simplify the results:

[tex]\begin{gathered} f(9)=81-9-2 \\ =81-11 \\ =70 \\ \implies f(9)=70 \end{gathered}[/tex]

The value of f(t) when t=9 is 70.
