When asking for they are basically asking you to evaluate the function
for -2, find a y value, and plug in that value as x in
Let's do it step-by-step:
1. Find the value of g(-2).
G(x) is given as a graph, therefore, you will have to see what value of axis y marks the graphic when you make x=-2. <em>Check the attached image</em>. As you may notice, the value that function g(x) generates for x= -2 is y= -3. Hence, g(-2)= -3.
2. Substitute the value into f(x).
F(x) is a piecewise function, so we'll need to determine the group the value fits into and calculate with the expession that corresponds for that value. Our value is -3, this value is less than -2, therefore, the function we'll have to use is .
3. Determine the value of f(-3).
Since f(x)= 7 for our value (-3), the result is 7.
4. Express your answer.

Answer:
0.1151
Step-by-step explanation:
Given that a laptop company claims up to 10.1 hours of wireless web usage for its newest laptop battery life. However, reviews on this laptop shows many complaints about low battery life. A survey on battery life reported by customers shows that it follows a normal distribution with mean 9.5 hours and standard deviation 30 minutes.
If X is the battery life then X is N(9.5, 0.5)
(we convert into one unit for calculations purpose here hours)
a) the probability that the battery life is at least 10.1 hours
=
we get the probability that the battery life is at least 10.1 hours is 0.1151
Answer:
We have the equation,
i.e.
i.e.
It is required to find a system of equations having infinite solutions.
We know that,
'When the equations are dependent or their graphs are same, the system of equations has infinite number of solutions'.
So, we can take any equation having same graph as that of .
Let, us take
So, from the graph of these equations below, we get the system of equations having infinite solutions as,
and
.
