The table below shows the average temperatures of the crust, the mantle, and the outer and inner core of Earth arranged randomly: Average Temperature of Layers Unknown Layer Average Temperature (°C) A 4,500 B 1,300 to 2,500 C 5,000 D 0 to 1,300 Which layer is most likely the mantle? Layer A Layer B Layer C Layer D
the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.
it solely depends on b, whether the function will have one or two or zero x intercept.
this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.
1- if b is zero, the graph will have exactly one x-intercept, at x= -a
2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.
3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.
∴ the statement is sometimes true.
in addition to being able to metabolize, grow, digest food, and excrete wastes, what other functions must an organism perform if it is to survive? survival also depends on the ability to maintain one's boundaries, to move, to respond to stimuli, and to reproduce. oxygen is a survival need.
