Create a rational function with a linear binomial in both the numerator and denominator. Part 1. Graph your function using technology. Include the horizontal and vertical asymptotes and the x- and y-intercepts on your graph. Label the asymptotes and intercepts. Part 2. Show all work to identify the vertical asymptote, the x-intercepts, and the y-intercept.

    yes so we have x + 2 ----- 3x + 4 you can use desmos to graph this

    https://www.desmos.com/calculator/5qfhpf8bgt asymptotes are breaks in the graph

    you see that the x intercept is at (-2,0)

    y = 0.5 they want the coordinates of the point which is x = 0 y = 0.5 or (0,0.5)

    now the vertical asymptote is the line between where the vertical parts of the go 'off the page'

    thats between x = -1 and x = -2 and its difficult to get from the graph vertical asymptotes occur when the denominator is zero so we can work it ouT:- 3x + 4 = 0 3x = -4 x = -4/3 or about -1.33

    should i put x-intercept also ?

    to work it out we put (x + 2) / (3x + 4) = 0 so x+ 2 = o and x = -2 x intercept at (-2 , 0)

    put x = 0 in ( x +2) / (3x + 4)

    because at the intercepts x = 0

    so (0+2) /3(0) + 4)? (2)/ (0+4) 2/4 1/2?

    yes - which is what we read off on the graph

    and also the vertic asymptotes is -4/3 OR about -1.33 right but what about the horizontal ?
