Problem 4 An exponential function is defined by k(20) = 15.2.
1. Show that when x increases from 1 to 1.25 and when it increases from 2.75 to 3, the value of k
grows by the same factor.
2. Show that when x increases from t tot +0.25, k(t) also grows by this same factor.
(From Unit 4 Lesson 5)

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
