What is i + 6i simplified?

Given f(t) = 282 - 53 +1, determine the function value f(2). do not include f(z) = in your answer

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.

Y=(x+3)(x-4)(x+1)^2 sulutions? multiplicity?
