Answer:
Th Range is [0, -∞)
Step-by-step explanation:
f(x) = 2 - x
w(x) = x - 2
We want to find the range of (f * w)(x).
First, we need to find (f * w)(x), which is the multiplication of the function f(x) and the function w(x). Lets use algebra to find (f * w)(x):
This is a quadratic function (U shaped), or a parabola. The graph is attached.
The range is the set of y-values for which the function is defined.
We see from the graph that the parabola is upside down and the highest value is y = 0 and lowest goes towards negative infinity. So the range is from 0 to negative infinity. Or,
0 < y < ∞
In interval notation, that would be:
[0, -∞)
No need to apologize, that's why we're here.
Rectangular prism, 25x10x8
The surface area is the sum of the area of all the surfaces. We have 2 surfaces that are 25x10, two 25x8 and 2 10x8 so our total surface area is
2(25(10) + 25(8) + 10(8))=2(250+200+80)=2(530)=1060, choice B
Red marble, 15 out of 40, 15/40 = 3/8, choice B again
There's really not enough information to answer unless we assume the only ways Bart washes his car is the gas station or himself. Assuming that, the probability he washes it himself is 1 minus the probability he washes at the gas station.
