Answer: 4.76 hours
Answer:
A
Step-by-step explanation:
We know the y intercept is positive so that eliminates choice D.
y = 3x^2 -2x+1
This does not intercept the x axis
y = 3x^2 -6x+3
= 3(x^2 -2x+1)
3(x-1)^2
This intercepts the x axis at 1
This is not the equation for the graph
y = 3x^2 -7x+1
Let x = 1
y = 3-7+1
= -3
This will cross the x axis, so this cannot be the graph
This is not really an equation that can be used to model anything as there is only one variable. see this.
1.25x-0.75x = 50
0.5x = 50
x=100
It can be solved and therefore does not have an input and an output required to model anything
