Tf ifa and b are similar matrices, then at=bt

Step-by-step explanation:

We know that for two similar matrices and exists an invertible matrix for which

" alt="B = P^{-1} AP" />" />

∴

Also

and

∴

so,

ddd

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
