As simple as it can go is As it's multiplied out form, which is -42.
slope = 
the slope is the value of f' (36)
f(x) = √x = 
f'(x) =
= 
f'(36) =
= 
2a+4(7+5a)
Distribute 4 into 7 and 5a
2a+28+20a
Combine like terms
Final Answer: 22a+28
Answer:
R1 = {(1, 7) (2, 7) (4, 7) (6, 7)}
R3 = {(x, y) (y, z) (z, t) (t, v)}
R1 and R3 are functions because first element in the ordered pair is not repeating, i.e they have unique images
