Turn x-4y=14 into slope-intercept form

If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

Which is the graph of f(x) = (4)x? image for option 1 image for option 2 image for option 3 image for option 4

For the quadratic function [tex]y=(x+4)^2-1[/tex] , do the following: a) rewrite the function in the standard form, b) rewrite the function in intercept form, c) find the vertex, d) find the y-intercept, e) find the x-intercepts.
