Answer:
Step-by-step explanation:
A relation is a function if there are no shared x values. If you look at the y-axis where x = 0, you can see that there are 2 coordinates that share that x value:
(0, -1) and (0, 3). Because the x value in both those coordinates is the exact same number, this is NOT a function, merely a relation. ALL functions are relations, but not all relations are functions.
The domain asks for all the included x values. It goes from the lowest x value to the highest x value. Our lowest x value is -4 and the function stops at an x value of 4. So the domain is
D = {x | -4 ≤ x ≤ 4}
The range goes from the lowest y value to the highest y value. Our lowest y value is -2 and the highest y value is 4. So the range is
R = { y | -2 ≤ y ≤ 4}
That straight line that comes after the first x and y is the line that translates to "such that". In words, our domain reads "x such that x is greater than or equal to -4 and less than or equal to 4" and the range reads "y such that y is greater than or equal to -2 and less than or equal to 4".
Answer:
16.5
Step-by-step explanation:
60 minutes = 1 hour
20 minutes * 3 = 60.
That means, by multiplying by a factor of 3, we can see exactly what Carrier's pg/hr speed is.
5.5 * 3 = 16.5
(1+i)/(1-i)
(1+i)/(1-i) • (1+i)/(1+i)
(1+i)(1+i)/(1-i)(1+i)
(1+2i+i^2)/(1+i-i-i^2)
(1 + 2i - 1)/(1 - i^2)
(2i)/(1 - (-1))
(2i)/(1 + 1)
2i/2
i
Answer:
g(x)=3^x-4, this one is exponential so it would have the greatest rate of change as x approaches infinity. The first one is a line and the third one is a parabola.
