Answer: Option C. [0.95, 1.59].
Step-by-step explanation:
We know that the mean is:
M = 1.27
and the margin of error is:
e = 0.32
This means that the actual value can be at a maximum distance of 0.32 from the mean.
then the interval will be:
[M - e, M + e].= [1.27 - 0.32, 1.27 + 0.32].= [0.95, 1.59].
The correct option is C.
Answer:
f(x)=a(x - h)2 + k
Much like a linear function, k works like b in the slope-intercept formula. Like where add or subtract b would determine where the line crosses, in the linear, k determines the vertex of the parabola. If you're going to go up 2, then you need to add 2.
The h determines the movement horizontally. what you put in h determines if it moves left or right. To adjust this, you need to find the number to make the parentheses equal 0 when x equals -2 (because moving the vertex point to the left means subtraction/negatives):
x - h = 0
-2 - h = 0
-h = 2
h = -2
So the function ends up looking like:
f(x)=a(x - (-2))2 + 2
Subtracting a negative cancels the signs out to make a positive:
f(x)=a(x + 2)2 + 2
