Compare the graph of f(x)=-2(0.5)^x to the parent graph of g(x)=5^x. Describe the domain and range of f(x). PLEASE HELP NOWWW!

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.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
