Answer:
The option that no represent a linear function is
Step-by-step explanation:
we know that
The graph of a linear function is a straight line
The equation of a linear function in slope intercept form is equal to
where
m is the slope
b is the y-intercept
<u><em>Verify each case</em></u>
option 1) we have
This option represent a linear function
where
m=3
b=-2
option 2) we have
This option represent a linear function
where
m=1
b=0
This option represent a linear direct variation function
option 3) we have
This option not represent a linear function
This option represent a exponential function
option 4) we have
This option represent a linear function
where
m=3
b=0
This option represent a linear direct variation function
Answer: Option D
Step-by-step explanation:
For a quadratic function of the form
The x coordinate of the vertice is:
In this case the function is:
So
The x coordinate of the vertice is:
The y coordinate of the vertice is:
The vertice is: (-3, -11)
The form e vertice for a quadratic equation is:
Where
the x coordinate of the vertice is h and the y coordinate of the vertice is k.
Then h=-3 and k =-11
Finally the equation in vertex form is:
