Sickle cell disease causes red blood cells to be crescent-moon-shaped. Sickle cell is caused by a DNA mutation that leads to a mutation in the hemoglobin protein. Surprisingly, the sequence of amino acids in the sickle cell hemoglobin has just one different amino acid compared to to the normal hemoglobin protein. (A Glu is changed to a Val). What type of DNA mutation is MOST likely the cause of this protein mutation

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.

ever get the answers? im stuck on this as well
