Determine whether these two functions are inverses.
1 answer:
Answer:
No The reactions are not inverses to each other
Step-by-step explanation:
f(x) = 3x + 27
Let f(x) be y
y= 3x+27
subtracting 27 on both sides
3x = y - 27
x= (y-27)/3
= y/3 - 9
inverse function is x/3 -9 not x/3 + 9
Therefore, not an inverse

Answer: cos(x) = 0
Good luck !
Step-by-step explanation:
x² + 3x - 15 = 2x - 13
x² + x - 2 = 0
(x + 2)(x - 1) = 0
By zero product rule, (x + 2) = 0 or (x - 1) = 0.
Hence x = -2 or x = 1.
