Which statement is true of this function?

f(x)=(1/5)^x-2

a. as the value of x increases, the value of f(x) moves toward a constant.

b. the domain of the function is (-2, ∞).

c. the function has a y-intercept at (0,-2).

d. the function is increasing.

  A.  As the value of x increases, the value of f(x) moves toward a constant

Step-by-step explanation:

An exponential function with a base less than 1 will decay to zero. Here, the exponential has -2 added to it, so the decay is toward the value -2.

An exponential function is defined for all real numbers. This one has a y-intercept of -1.

the thermometer is precise but not accurate

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
