Step-by-step explanation:

The matrix

has eigenvalues
such that





for all values of
, so we need to have
in order for
to be real-valued. This happens for

where
is any integer, and over the given interval we have
and
.
I believe it is f(x) = 4x + 4. It is basically slope intercept notation, just with the function sign in front of it acting as the Y variable.
Answer:
C
Step-by-step explanation:
6 * 5 = 30
3*4 = 12
30 + 12 = 42
