Find the equation of the quadratic function F whose graph is shown below.<br> F(x) = ?
zepelin [54]

Answer:

y = x² - 2x - 3

Step-by-step explanation:

y + 4 = C(x - 1)²

To determine C, use x = 4, y = 5

5 + 4 = C(4 - 1)²

9 = 9C, C = 1

y + 4 = (x - 1)² = x² - 2x + 1

y = x² - 2x - 3

4)
3x-2y=10
5x+y=4

We solve this system of equation by elimination method.
   3x-2y=10
2(5x+y=4)
------------------------
13x=18

Answer: A)  13x=18

5)
slope-intercept form:
y=mx+b
y=f(x)

m=slope
b=y-intercept

1) we calculate the slope:
we choose any two points of this table:
For example: (2,2) and (3,4)

Given two points (x₁,y₁) and (x₂,y₂) the slope of the line that passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)
In this case:
m=(4-2)/(3-2)=2

2) we compute "b";
we choose an any point of this talbe:
For example: (4,6), and we substitute "x" for "4" and "y" for "6" in the next equation:
y=2x+b  
6=2(4)+b
b=6-8
b=-2

3) we build the function that it belong this table:
m=2
b=-2
f(x)=mx+b
f(x)=2x-2

Answer: B) f(x)=2x-2
