The domain is -∝ < x < ∝, the range is g(x) > 0, and the asymptote is g(x) = 0
<h3>How to plot the graph?</h3>
The exponential equation is given as:
g(x) = 3^(x+2)
Next, we plot the graph using a graphing calculator
See attachment for the graph of the function g(x) = 3^(x+2)
The function can take any value of x.
So, the domain is -∝ < x < ∝
Also, we have
g(x) = 3^(x+2)
Rewrite as:
g(x) = 3^x * 3^2
Set the exponent to 0
g(x) > 0 * 3^2
This gives
g(x) > 0
So, the range is g(x) > 0, and the asymptote is g(x) = 0

Answer:
40 gallons of water and 140 gallons premium antifreeze
Step-by-step explanation:
Let p represent the number of gallons of premium antifreeze in the mix. Then 180-p is the number gallons of water. The amount of pure antifreeze in the mix is then ...
0.90p + 0·(180 -p) = 0.70·180
p = 0.70·180/0.90 = 140 . . . . divide by the coefficient of p
180-p = 40 . . . . . find the water content
40 gallons of water and 140 gallons of premium antifreeze are in the mix.
Answer:
it cost $39.95 in a month when you use the internet for 14 hours
Step-by-step explanation:
internet company charges $4.95 per month plus $2.50 for each hour
Let x be the amount of hours internet used
for 1 hour, charge is 2.50
for x hours , charge is 2.50x
To get linear equation we use y=mx+b
m is the slope and b is the fixed cost
fixed cost b= 4.95 and slope m = 2.50
So equation becomes y = 2.50x + 4.95
we need to find the cost y for 14 hours
So we plug in 14 for x and find out y
y = 2.50(14) + 4.95= 39.95
