What will be the dimensions of the new matrix formed by multiplying a 3 x 4 matrix and a 4 x 1 matrix?

The 2 middle values (4 and 4) must be identical in order to multiply their matrices.  The size of the resulting matrix is the outer values.
[3 x 4] x [4 x 1] = [3 x 1]

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
