Answer:
d.
Step-by-step explanation:
Left line is defined when x < 1 (x is less than 1). The point is not full and that means that x = 1 is not included.
Right line is defined when x is greater or equal to one x ≥ 1.
Options that have x < 1 and x ≥ 1 are b and d, so the answer is one of those.
Equations of the lines are in slope-intercept form y = mx + b, where m is slope and b is y-intercept.
Right line has steeper slope than left line, so the slope of right line will have bigger absolute value. That is the case with option d. (Left line has slope -1 and right one has slope -2, absolute value of right slope is bigger.)
You could also check with y-intercepts. Left line has y-intercept at y = 2 and left line is defined when x < 1. Only option d meets these conditions.
If you want the intersect of M and N, then:
M∩N = {4,7} (common part in M AND N)

Answer:
The temperature at 9:00 is 14° C.
Step-by-step explanation:
At noon, the temperature was 6° C.
By 5:00, the temperature had dropped to -2° C.
Every hour until 9:00, the temperature rose 4°, so 4•4 is 16.
16 + -2 is 14.
So, the temperature at 9:00 is 14° C.
The exponential function with a growth factor has a rate greater than 1
The percentage growth rate is 276%
<h3>How to determine the percentage growth rate?</h3>
The growth factor (b) is given as:
b = 3.76
The growth factor (b) is greater than 1.
So, the percentage growth rate (r) is calculated as:
r = b - 1
Substitute known values
r = 3.76 - 1
Evaluate the difference
r = 2.76
Express as percentage
r = 276%
Hence, the percentage growth rate is 276%
