well, is noteworthy that an x-intercept is when y = 0 or namely is a solution or root of the quadratic, so we know then that the x-intercepts or solutions are at (-1,0) and (3,0), that simply means that

Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day!
Answer:
4:1
Step-by-step explanation:
you can take the smaller number and divide it by the larger number in this ratio, and the lowest number that you can have is a 1 so this is the only answer that makes any sense.
<h2>Please mark me the brainliest!!</h2>
Answer:
like here x= 3 and y= -15
here, its 5 times goes in negative
now if y = 10 TO X IS 5 TIME POSITIVE HERE = 10×5 = 50
