At the beginning of an experiment, there are 500 grams of contaminants. Each hour, one fourth of the contaminants are filtered out. How many grams of contaminants remain after 4 hours? Show all your work for full credit.

Round your answer to the nearest hundredth. Use ^ for exponents. x^2 = x2 Consider the exponential function g(x) = 1,296x .

Find the output values for x-values x = –1.75, –1, –0.25, 0, 0.25, 0.50, 0.75, and 1.

answer:      

step-by-step explanation:

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
