The function f(x)=2x-1 is defined for -3≤ x≤ 5. Find the range of f(x). The equation of f^-1(x). Sketch the graphs of f(x) and f^-1(x) on the same diagram and find which the line where the 2 graphs are symmetrical.

answer is 67%

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
