Please help :( Imagine yourself as a naturalist. In your travels, you observe the toad and frog

shown here. Write two questions that might arise from these observations.

1. What is the relationship between body shape and the habitat where they are most commonly found?

2. What is the difference between toads having a thicker skin than frogs?  

Explanation:

Toads and frogs are amphibians that belong to the same family, live in lakes, rivers and wetlands and have some similar characteristics. Among their main differences are:

Given these observations, two questions that may arise could be:

1. What is the relationship between body shape and the habitat where they are most commonly found? This is that frogs have longer legs which helps them to swim and that is why they are more commonly found in water. While toads have shorter legs that even allow them to burrow into the ground, they can survive longer on land.

2. What is the difference between toads having a thicker skin than frogs?  Toads have thicker and more impermeable skin than frogs, which allows them to live in drier places. Also, the blood of the toad is of higher osmotic concentration than water.

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.
