The roots: this is when y=0, so in yours there are 2 roots. Just look at the x value when y=0 and that is your roots.
Y intercept- this is when x=0, so just look at the y value below x=0 and that is the y intercept. Note the answer will probably be in the form (0,_)
Vertex=do you see a pattern? Well the vertest would be the highest or lowest point of the quadratic equation. Your vertex would be (5,-9) because just look at x=4 and x=6, bit of the y values are -8 and when you look at x=3 and x=7 they are also the same because this is a quadratic equation.
Max or min: yours is a minimum because (5,-9) is the lowest point. Every value left and right of this are higher up the graph, so this would be a minimum.
*something that will help you see this all more clearly is if you graphed this or put it into Desmos to see the vertex etc.
Answer:
yes it is hard
Step-by-step explanation:
Most people don’t really learn statistics until they start analyzing data in their own research.
Answer:
She sells four loaves of bread.
Step-by-step explanation:
First, convert you fractions to decimals.
13 1/2 = 13.5
2 1/4 -2.25
Next, divide 13.5 by 2.25.
13.5/2.25=6
Two thirds of 6 is 4.
Therefore, the baker sold four loaves of bread.
