so, is decaying at a rate of 0.5 or 50%, notice, since is a decay rate, is negative.
Answer:
The function f(x) = IxI works as follows:
if x ≤ 0, then IxI = -x
if x ≥ 0, then IxI = x
notice that if x = 0, then I0I = 0 = -0
Now, we want that:
IxI = x
Then we have that x must be greater or equal than zero:
x ≥ 0.
To represent it in the number line, you should use a black dot in the zero an shade all the right region:
__-2__-1__0__1__2__3__4__5__6__....
<em>The vertex for f(x) = 1/2 x2 + 3x +3/2 is:</em>
<u><em>(-3,-3)</em></u>
Answer:
y = -4/3x + 20
Step-by-step explanation:
2x + 1.5y = 30
1.5y = 30 - 2x
y = 20 - 4/3x
y = -4/3x + 20
-9 + 5c + 18 - c = 37
4c + 9 = 37
4c = 37 - 9
4c = 28
4c/4 = 28/4
c = 7
hope this helps
