The quadratic formula works for every quadratic equation, with no exception. Other methods are often tedious and time-consuming, such as completing the square, and others don't work in all situations, such as factoring. Being universal, the quadratic equation becomes an essential tool to solve any quadratic function with little to no thinking, due to the simple solving nature of it.

Answer:
Opens up.
Step-by-step explanation:
See the 2 in front of the x? If that's positive, it opens up. If it's negative, it opens down.
Answer:
y= 1x - 1
Step-by-step explanation:
Slope-intercept form: y=mx + b
(-4,-5) (5,4)
m= (y2 - y1)/(x2 - x1) = (4+5)/(5+4)=1
4=1(5)+b
4=5 + b 4-5=b b= -1
y= 1x - 1
Answer:
16
Step-by-step explanation:
a/(1 - r)
= 8/0.5
= 16
