2 + 2 x 4 - 16 = -6
How?
Use PEMDAS.
The first step that shows up is multiplication.
2 + 8 - 16
Next comes Addition.
10 - 16
-6
It’s A I just took that trust me
Answer:
The graph is positive and decreasing for all real values of x where x < -1
Step-by-step explanation:
we have
![f(x)=(x-3)(x+1)](https://tex.z-dn.net/?f=f%28x%29%3D%28x-3%29%28x%2B1%29)
The function is a vertical parabola open up
The roots (x-intercepts) are x=3 and x=-1
The vertex is the point (1,-4 ) is a minimum
using a graphing tool
see the attached figure
we know that
In the interval (-∞,-1) ---> the function is positive and decreasing
In the interval (-1,1) ---> the function is negative and decreasing
In the interval (1,3) ---> the function is negative and increasing
In the interval (3,∞) ---> the function is positive and increasing
therefore
The graph is positive and decreasing for all real values of x where x < -1
