This stuff is way to hard
Answer: No. You reversed the domain and range
#2) B) x ≥ 0
#3) B) [0, ∞)
<u>Step-by-step explanation:</u>
#2 is asking about the domain, which is all of the x-values.
The graph appears to be touching the y-axis so it equals 0 and all other x-values are greater than zero. (0, 1), (1, 0), (2, -0.8), (3, -1.5), etc. All of the x-values are moving toward the right, which is positive infinity. --> x ≥ 0
#3 is asking for the range, which is all of the y-values.
The vertex is at (0, 0) and all other y-values are above zero (positive numbers), moving toward positive infinity. --> [0, ∞)
In total, the water level in Wei's pool increased by four centimeters. first, you would take negative one and nine-tenths, then you would add the three and one-half increase. This would give you one and six-tenths. You would then also add the two and four-tenths increase, leaving you with four.
In the table, it shows the x values and the corresponding y values under it [aka f(x)].
The problem is basically asking which equation, a,b,c or d will get the y values with the x values.
we can try this with x value 3 and y value 7
a. 3^x=3^3=3*3*3=27
27 is so far away from 7 so a must be wrong
b.3x=3*3=9
still not 7 therefore b is also wrong
c. 2^x-1= 2^3-1=8-1=7
7=7 therefore this one might be right, but to make sure we have to check if d is correct or not
d. 2x+1=2*3+1=7
7=7 so d is also correct for the first set of values.
Next we should use the next available values until one of the answers c or d is confirmed wrong
x value 4 and y value 15
c. 2^4-1=16-1=15
15=15
d. 2x+1=8+1=9
9 does not work
Therefore, the answer should be c.
