In which group would you put pasta and breads according to the mypyramid plan?

Grains group

Explanation:

MyPyramid is a plan by the US government which has a set of recommendations to be followed for a diet and exercise and these are based on the dietary guidelines for Americans 2005. 

The MyPyramid plan is intended to make the American citizens more aware of the nutrition that they are getting and the food they are eating. 

There are a total of 7 categories in which the recommendations are made and these are: grains, vegetables, fruits, milk, meat and beans, oils, discretionary calories, and physical activity.

Out of these the pasta and bread are placed in the grains category. 

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.
