Answer:
The 3rd and the 5th
Step-by-step explanation:
The graphs of the 3rd and the 5th functions are straight lines
The 1st and 2nd are parabolas
The 4th is an exponential
You must look at the graph: it shall include all the real values for the y coordinate
You can solve with the formula for cuadratic equations:
x=−b±√b2−4ac
2a
Slope = 70,000
point: (8,2000000)
Form: y = mx + b
2000000 = 70,000*8 + b
b = 3.57
EQUATION:
Profit = 70,000(year after 1990) + 3.57
A 180º rotation around the origin changes the coordinates from (x, y) to (-x, -y).
A translation 7 units up increases the y value by 7 units.
A reflection over the x-axis results in the y-values being opposites.
