the upper quartile is 160
Vertex form should be : y = (x+1)^2 - 2, where the vertex is (-1,-2)
Answer:
The answer to your question is number 3.
Step-by-step explanation:
Data
slope = m = 2
Point = (3, 9)
Process
1.- Write the equation of the line in the form point-slope
y - y1 = m(x - x1)
2.- Identify the values of x1 and y1
x1 = 3 y1 = 9
3.- Substitution
y - 9 = 2(x - 3)
4.- Simplify
y - 9 = 2x - 6
y = 2x - 6 + 9
5.- Result
y = 2x + 3 slope y-intercept form
1.9 is greater bc there is a whole number
Hope this helped!!!!
I'm not good at math but I think is 3f because you'll be multiplying f(unknown #) by 3 so f(x) would be 3f
