What is the domain of the exponential function shown below? f(x) = 5 • 3x
2 answers:
Answer:
Domain is (-∞,∞)
Step-by-step explanation:
Given f(x) is an exponential function
Domain is the set of x values for which the function is defined
For domain we need to check for the restriction of x
x can take any positive and negative values
there is no restriction for x because it is in exponent
So domain is set of all real numbers
Domain is (-∞,∞)

Answer:
<h3>The ratio of technicians to all helpers is 11 : 7, orStep-by-step explanation:
- Given that there are 7 ushers and 11 technicians helping at the Harper Middle School fall play.
- Let x be the number of ushers ( or helpers ).
- Therefore x=7 helpers.
- Let y be the number of technicians.
- Therefore y=11 technicians.
That is to find the ratio of y to x.
We can write the ratio of technicians to all ushers(helpers) as y : x
Which implies that 11 : 7, (since y=11 and x=7)
Or or 11 to 7
