267 x 0.02 = 5.34
267 + 5.34 = 272.34

267 x 0.08 = 21.36
267 - 21.36 = 245.64


267 + 272.34 + 245.64 = $784.98

Stells [14]

Answer: down there

Step-by-step explanation:

When solving a radical equation, it is important to always check your answer by substituting the value back into the original equation. If you get a true statement, then that value is a solution; if you get a false statement, then that value is not a solution.

Which statements accurately describe the function f(x) = 3(16) superscript three-fourths x? select three options.
sineoko [7]

Range for the given Exponential function f(x) = 3(16)^{{\frac{3}{4}x} is f(x) > 0.

the correction option is a). f(x) > 0

The function given in, the question is exponential function is given by
f(x) = 3(16)^{{\frac{3}{4}x}  Which is an exponential function. The domain of the  give function is (-∞, ∞).

<h3 /><h3>what is exponential function?</h3>

The function which is in format f(x) =  a^{x} where, a is constant and x is variable,  the domain of this exponential function  lies   (-∞, ∞).  

the Question seems to be incomplete. And options could be
a) f(x) > 0              c) f(x) ≤ 0
b) f(x) < 0              d) f(x) ≥ 0

Simplification of the given equation
f(x) = 3(16)^{{\frac{3}{4}x}      
f(x) = 3(2^4)^{{\frac{3}{4}x}
f(x) = 3(8)^{x}

clearly, the range of the exponential function is f(x) > 0.
