Answer:
90
Step-by-step explanation:
Answer:
Option B.
Step-by-step explanation:
The given table of values is
x f(x)
-3 -2
-2 0
-1 2
0 2
1 0
2 -8
3 -10
4 -20
We need to find the interval for which the function f(x) is positive.
From the given table it is clear that the value of function f(x) is negative before -2 and after 1.
The function positive between x=-2 and x=1. So, we can conclude that the function f(x) is positive for the interval (-2,1).
Therefore, he correct option is B.

Answer:
y = 1/2x +4
Step-by-step explanation:
You are given the slope (m) of the line and a point, and asked for slope-intercept form:
y = mx +b . . . . . . . line with slope m and y-intercept b
The value of the intercept, b, can be found from the point by rearranging this equation to ...
b = y -mx
b = 1 -1/2(-6) = 4 . . . . using x=-6, y=1
Then the equation of the line with m=1/2 and b=4 is ...
y = 1/2x +4
