Dump the soil and water from the first experiment into a small bucket. Rinse the glass, and get out a second glass. In this experiment, you will test the acidity of the soil. Pour ½ cup of soil into each glass. Slowly pour vinegar onto the soil in one glass, stopping when the glass is full. Slowly pour the baking soda solution onto the soil in the other glass until that glass is full. Record any reaction you see. If there is no reaction, write that down.

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.
