What I the range of f(x)=4^x? A. all positive real numbers
B. all real numbers
C. all real numbers grater that or equal to 4
D. all real numbers grater than 4

We conclude that the range of the function is 'all positive real numbers'.

Thus, option (A) is true.

Step-by-step explanation:

Given the expression

Determining the domain:

The domain of a function is the set of input values for which the function is real and defined.

It is clear that the given function has no undefined points nor domain constraints.

Therefore, the domain is: -∞ < x < ∞

Thus,

Determining the range:

The range is the set of values of the dependent variable for which a function is defined.

We know that the range of an exponential function of the form

In other words, the range is all positive real numbers.

Thus,

Therefore, we conclude that the range of the function is 'all positive real numbers'.

Thus, option (A) is true.

the answer i believe is 27 units.

step-by-step explanation:

meaning of term low   inflation is when prices of commodities does not change very highly.so low inflation is   not a sign of healthy economy.the demand of goods becomes higher due to some faulty measures taken by government

there are two kind of inflation

1. positive inflation : when supply of goods is less than prices of those goods rise.

2. negative inflation : when supply of any good is very high so it,s price will fall.

so option c is true : struggling economy because it results from a steady rise in demand.
