Can you make a sketch of a parabola if you ONLY know where its y-intercept is? For example, if the y-intercept of a parabola is (0,−8), can you sketch its graph? Why or why not? EXPLAIN below, USING WORDS (more than yes/no)

Question 2
2.
What about two x-intercepts of a parabola? If you only know the x-intercepts, can you sketch the parabola? For example, if the x-intercepts are (−3,0) and (5,0), can you sketch the parabola? EXPLAIN below, USING WORDS (more than yes/no)

Question 3
3.
Can you make a sketch of a parabola with only two x-intercepts and the y-intercept? To test this idea, sketch the graph of a parabola that has x-intercepts (−3,0) and (5,0) and y-intercept (0,−8). EXPLAIN below, USING WORDS (more than yes/no)

Finding the y-intercept! Finding the y-intercept is a lot easier than finding the x-intercepts (which we will do tomorrow).
