The graph shows the maximum amount of water vapor that air can hold at different temperatures. y 100 90 80 70 60 Water Vapor Density (g/m") 40 maximum humidity 20 -10 х 5 10 15 20 25 30 35 40 45 Temperature (degrees Celsius) Beth's hygrometer is reading a temperature of 30°C and a relative humidity of 6596. The humidity in the air is grams/cubic meter. 38.5 30 19.5​

where is the scientific experiment?

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

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.

idk about that one.
