Please help me on this question

a) upward

b) x-intercepts at x= -4, -2

y-intercept at y = 8

c) x = -3

d) (-3, -1)

Step-by-step explanation:

after the answer to the other, very similar question you should be really able to do this one.

all is really visible.

please refer to my other answer for more details about the reasons.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
