Answer:
-1
Step-by-step explanation:
We need to find the value of tan² 70° -sec² 70°.
We know that,
 ...(1)
 ...(1)
We can write the given expression as :
tan² 70° -sec² 70° = -(-tan² 70° +sec² 70°)
=-(sec² 70°-tan² 70°)
Using identity (1)
=-(1)
= -1
Hence, the value of the given expression is -1.

Answer:
input:                    x+4                   output        (x,y)
-2                        -2 + 4 =2               2             (-2,2)
0                          0 + 4 = 4              4              (0,4)
2                           2 + 4 = 6              6             (2,6)
...
Step-by-step explanation:
continue by plugging in x to the equation, x is input and y is output 
then just plot your (x,y) points on the graph.
