1 answer:
The question provided states that,
George took a direct flight from Dallas to Los Angeles covering 1,233 miles. Initially, the plane was traveling at a speed of 460 miles per hour for the first 75 minutes, then at a speed of 439 miles per hour for the remaining duration.
Let x denote the hours during which the flight flew at 439 miles per hour.
Based on this, we can establish the following:
To convert this into minutes, we must multiply by 60, resulting in

Answer : y>0
f(x) = 9*2^x
This function is exponential in form
Substituting positive numbers for x yields positive y values
Substituting negative numbers for x also results in positive y values
Therefore, y remains positive regardless of the value of x.
The range comprises all possible y outputs of the function
Since y is always positive, the range is y > 0
