g(x)= -|x+2| -1
The domain is the input values, or x values
it is all real number
The range is the output values, or g(x)
the absolute value at is smallest is 0
0-1 is -1 this is the max since the absolute value is multiplied by -1
g(x) <=-1
the output is less than or equal to -1
Answer:
Step-by-step explanation:
The distance between a point (x,y) and the point (-3,4) is
d1= .
The distance between a point (x,y) and the point (0,0) is
d2= .
You know what y is from the equation of the line, so substitute that, set d1=d2, and solve for x.
Answer:
3
Step-by-step explanation:
Find the concavity changes of f(x).
Give the x-coordinates.
So, the answer to the multiple choice question is -1 and 5 since those points are where f''(x) changes sign.
Note: You can tell that you're supposed to find the concavity changes of f(x) and not f''(x) because from the graph it's obvious that the concavity of f"(x) doesn't change.
The point-slope form:
We have m = -4 and the point (-2, 5). Substitute:
<em>use distributive property</em>
<em>add 5 to both sides</em>
