Answer:
Step-by-step explanation:
f(x) = x2 + 2x - 2 should be rewritten using " ^ " to indicate exponentiation:
f(x) = x^2 + 2x - 2.
We find a couple of key points and use the fact that this parabola is symmetric about the line
-2
x = ----------- = -1. When x = -1, y = f(-1) = (-1)^2 + 2(-1) - 2, or 1 - 2 -2, or -3.
2(1)
Thus the vertex is at (-1, -3). The y-intercept is found by letting x = 0: y = -2. The axis of symmetry is x = -1.
Graph x = -1 and then reflect this y-intercept (0, -2) about the line x = -1, obtaining (-2, -2). If necessary, find 1 or two more points (such as the x-intercepts).
To find the roots (x-intercepts), set f(x) = x^2 + 2x - 2 = 0 and solve for x.
Completing the square, we obtain x^2 + 2x + 1 - 2 = + 1, or (x + 1)^2 = 3.
Taking the square root of both sides yields x + 1 = ±√3. One of the two roots is x = 1.732 - 1, or 0.732, so one of the two x-intercepts is (0.732, 0).
Answer:
B. Funds need to be easily accessible.
Step-by-step explanation:
We need to understand what is "rainy day", it is an idiom we use to describe a unexpected difficult situation that may happen, that is why we need to "save for a rainy day"
It important for a rainy-day fund to be highly liquid, it is an financial concept, the degree to which an asset can be bought or sold in the market without significantly affecting its market price such as cash, gold, CD... Which means the asset must be easy to access.
So in a rainy day, we need to response as soon as possible to handle the difficulty.
Hope it will find you well.
Answer:
m= -3/4
Step-by-step explanation:
m÷4+6= 3
m÷4= 3-6
m÷4= -3
m= -3/4
Answer:
A) y=3x+1
Step-by-step explanation:
Use the formula y=mx+b
m is the slope and b is the y intercept
the graph starts on 1 on the y axis so you replace 1 for b
the slope goes up 3 and over one, giving the fraction 3/1 or just 3. so you replace 3 for m.
