The graphs below show four functions: graph a shows function f of x equals 4 multiplied by 3 to the power of x. graph b shows function f of x equals 4 multiplied by 3 to the power of negative x. graph c shows function f of x equals 10 to the power of x. graph d shows function f of x equals 10 to the power of negative x. which graph best shows the function f(x) = 4(3)−x to represent the rate at which a radioactive substance decays? graph a graph b graph c graph d

Graph B shows function f of x equals 4 multiplied by 3 to the power of negative x.

Step-by-step explanation:

is the value 4 times three raised to the negative x. Graph B is the best representation.

i can

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
