Instructions: For each problem, complete a dihybrid cross and calculate the ratios of each genotype. Ex) A tall green pea plant (TTGG) is crossed with a short white pea plant (ttgg).
TT or Tt = tall
tt = short GG or Gg = green gg = white

your answer should be c) enjoy!

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.
