Answer:
[tex]12-t+6t^2[/tex]
Step-by-step explanation:
Find the one with the highest exponent 2.
[tex]12-t+6t^2[/tex] is the only one
h(t) = 12 -t+6t^2
A quadratic function has the highest power of the variable as 2 and must have a power of 2
h(t) has a power of 3
g(t) has a power of 3
k(t) has a power of 4
