The graph of f(x)= (0.5)^x is replaced by the graph of g(x) = (0.5)^x-k. if g(x) is obtained by shifting f(x) down 2 units, then what is the value of k?

a) k=2
b) k=1/2
c) k= -2
d) k= -1/2

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
