Question

graph the equation.
- 5/4 (x-1)(x+3)

Answer 1

Answer:

Step-by-step explanation:

So, to graph a parabola we must have at least 3 points, the x intercepts and the turning point. Currently the equation is in x intercept form which means that we know straight away (assuming the equation =0) that the x intercepts are:

(1,0) and (-3,0)

Now we have to find the turning point and we can do this by putting the equation into turning point form:

-5/4($x^{2} +2x-3$)

-5/4(($(x+1)^{2} -3-1$)

-5/4$(x+1)^{2}+5$

Now we can figure out the turning point which is:

(-1,5)

Graph those three points and you should get a parabola shape
