Which of these figures must be a rectangle? a. a trapezoid with at least one right angle b. a parallelogram with four congruent sides c. a trapezoid with two congruent sides d. a parallelogram with at least one right angle

D is the correct answer. 

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
