The answer would be one chance in seven.
Answer:
y=3x+1
Step-by-step explanation:
I'm very bad at explaining things so im sorry if this doesn't make any sense
the y axis goes up
the x axis goes sideways
to fill in the "y = ____x+_____"
you find a point on the line, see how far up it is from 0,0 and put that in the first blank space, in this case its 3. then you find how much it goes over on the x axis. in this case its 1 over. so you would put 1.
Answer:
As 
, 
.
Step-by-step explanation:
See the attached image for the graph of <em>f</em> .
As 
, the important part of the definition of <em>f</em> is the first part, valid for [0, 2). On the interval [1, 2), [x] = 1, so 
, and the slope is 1.
Interestingly, on the interval [2, 3), 
, making 
. As 
, the value of <em>f </em>' approaches 4. That accounts for the sudden change in direction at the point (2, 2) where the two pieces of the graph connect.
So although the pieces meet at (2, 2) -- <em>f</em> is continuous -- <em>f</em> does not have a (two-sided) derivative at that point because the left-hand derivative and right-hand derivative have different values. There's a "bend" in the graph.
6x + 11
Just add like terms
2(4x^2-3)-4
8x^2 -6-4
8x^2 - 10
8(1)^2 - 10
8-10
