Answer:
So minute hand will rotate in half an hour
Step-by-step explanation:
In one hour minute hand of clock rotate about 360°
So in half an hour minute hand clock rotate
We have to find how many minute hand rotate in radian
For conversion of degree to radian we have to multiply with
So
So minute hand will rotate in half an hour
Evaluate the function at the three values of the range and see what you get. The appropriate choice is ...
... D) {15, 3, 0}
_____
Evaluation can sometimes be simpler if you rearrange the function to a form called "Horner's form."
... f(x) = (x -4)x +3
Then the evaluation looks like (for x=-2) ...
... f(-2) = (-2-4)(-2)+3 = (-6)(-2) +3 = 12 +3 = 15
This is sufficient to identify D as the answer of choice.
Slope is rise over run, aka change in y divided by change in x:
Answer: -1
