a) The domain of a function refers to the set of values of x that satisfy the function. On the graph, it is between the minimum value of x on the left and the maximum value of x on the right. Since the line continues to the left and right, it tends towards infinity on both sides. Hence,
Domain = (- infinity, infinity)
b) The range of a function refers to the set of values of y that satisfy the function. On the graph, it is between the minimum value of at the bottom and the maximum value of y at the top. The maximimum value of y is - 1 and the minimum is negative infinity. Hence,
Range = (- infinity, - 1}
c) The x intercept is the value of x when y is zero. It occurs at the point where the line cuts the x axis. Since the line doesn't cut the x axis, there is no x intercept.
d) The y intercept is the value of y when x is zero. It occurs at the point where the line cuts the y axis. It cuts the y axis at x = - 4
Thus, y intercept = - 4
e) the function value, f(- 4) is the value of y at x = - 4. From the graph,
f(- 4) = - 2
the function value, f(0) is the value of y at x = 0. From the graph,
f(0) = - 4
Answer:
0
Step-by-step explanation:
L = 2W
A = 50
A = L x W
50 = 2W x W
50 = 2W^2
W^2 = 25
W = 5
so L = 2W = 2(5) = 10
P = 2(L+W)
P = 2(10+5)
P = 2(15)
P = 30
answer
P = 30 in
At 6pm, the temperature is -17 degrees Fahrenheit.
If you construct lines l, m, and n so that l is perpendicular and l is parallel to n
then the D) n is perpendicular to m.
