a giant sequoia tree is planted in trevor’s backyard when it is 2 ft tall. the tree grows an average of 4 ft each year. write a function and graph the height of the tree over this time period.

G(x)  = 2 + 4n is the growth function.

Step-by-step explanation:

The initial length of the tree planted in backyard =  2 ft

The average growth of the tree each year = 4 ft

Let n be the number of years taken into account any moment.

Hence the growth function G(x) =  Initial height + Growth each year

or, G(x)  = 2 + 4n  : here  n = number of years.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
