F(-1) = 3
How did I figure this out?
f(-1) is substituted for f(x) so you must look at -1 on the x axis.
Once you've located -1 on the x-axis, locate what it equals to answer the question.
The answer should be the y-axis number that corresponds to -1 which is 3.
Answer: y=3x+12
explanation: just add the 3x to the 12
Answer:
around 81.2 degrees
Step-by-step explanation:
use inverse tangent
remeber tan = O/H
divide it first
84/13
6.461538461538462
then use invese tan(
)
81.20258929000894
or around 81.2 degrees
