An eagle starts flying at an elevation of 42 ft. Elevation is the
distance above sea level. The diagram below shows the elevation changes during
the eagle's flight. Write an expression representing the eagle's flight. What is the
elevation at the brook?

Step-by-step explanation:

When an eagle gains the height, elevation of the eagle will be positive and when it goes down elevations will be negative.

Initial height of the eagle = 42 ft

Achieves the elevation = 144 ft

Goes down to 162 ft so the elevation will be = -162 ft

Gains the height again therefore, elevation of the eagle = 25 ft

Goes down to 65 feet so the elevation = -65 ft

Therefore, expression representing the eagle's flight will be,

(42 + 144 - 162 + 25 - 65)

Elevation at the brook = (42 + 144 - 162 + 25 - 65)

                                     = 20 ft

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.

it is 570
