Answer:
2nd answer option
Step-by-step explanation:
the domain is the interval or set of valid x values. the range is the same for valid y values.
so, what is the smallest x value we see in the functional graph ?
x = 0
there is no functional value for any x smaller than that.
and then the function goes on and on to the right in all eternity. that means it goes to infinity.
so, domain = [0, infinity)
please consider the round bracket at the end, because "infinity" is not a number.
now for the range and the y values.
in this case I start to ask for the largest y value.
y = 4
for no x value do we get a larger y value.
but it goes down and down in all eternity, going also to infinity, but -infinity (down is negative for y).
so, the range = (-infinity, 4]
"-infinity" is also not a number and therefore not included (hence the round bracket).

Answer:
Interest earned is $58.2
Amount in account is $544.2
Step-by-step explanation:
To calculate the simple interest, we make use of the simple interest formula.
Mathematically;
I= PRT/10”
whereI is the interest
P is the amount deposited which is the principal and is 485
R is the rate which is 3% or simply 3/100 = 0.03
T is time which is 4 years
Plugging the values, we have
I = (485 * 3 * 4)/100 = $58.2
The amount of money in the account will be the interest plus the principal.
This is $58.2 + 485 = $543.2
Step-by-step explanation:
12595000 * 100 = 1259500000%
