B is the answer when the parabola is facing down it is negative
vovangra [49]3 years ago
3 0

Answer:

The function is negative for all real values of x where x < -3 and x > 1.

Step-by-step explanation:

The values of the function are the y-values.  The y-values are positive from 3≤x≤1.  Everywhere else in the function, the y-values are negative.

This means that the function is negative from x < -3 and from x > 1.

On a piece of paper, graph this system of inequalities. Then determine which region contains the solution to the system.
Mashutka [201]

we have

y\leq \frac{1}{4}x+3 ----> inequality 1

The solution of the inequality 1 is the shaded area below the solid red line

The solution is the region D and region C

y\geq-x+5 -----> inequality 2

The solution of the inequality 2 is the shaded area above the solid blue line

The solution is the region B and region C

The solution of the system is the common area

so

The solution is the region C

see the attached figure

therefore

the answer is the option C

Region C

Y = -x^2 + 4x<br><br> quadratic formula
marin [14]

Answer:

Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Direction: Opens Down

Vertex:  

( 2 , 4 )

Focus:  

( 2 , 15 /4 )

Axis of Symmetry:  

x = 2

Directrix:  

y = 17 /4

x              y

0             0

1              3

2             4

3             3

4             0

To find the x-intercept, substitute in  

0  for  y  and solve for  x . To find the y-intercept, substitute in  0  for  x  and solve for  y .

x-intercept(s):  ( 0 , 0 ) , ( − 4 , 0 )

y-intercept(s):  ( 0 , 0 )
