Answer: A. f(g(x)) =x and g(f(x))=x and f and g are inverses.
Step-by-step explanation:
A function <em>g</em> is the inverse of function <em>f</em> if
<em>f(g(x)) = g(f(x))=x</em>
Given: f(x)= x+4 , g(x) = x-4
f(g(x)) = f(x+4) = (x-4)+4
= x-4+4 = x
i.e. f(g(x)) =x
g(f(x))= g(x-4) = (x-4)+4 =x
i.e. g(f(x))=x
Hence, f(g(x)) =x and g(f(x))=x and f and g are inverses.
Answer:
The result in standard form is: 
Step-by-step explanation:
Dividing the values:
To find the real part, we divide 2.645 by 1.15. So
2.645/1.15 = 2.3
Finding the power:
Its a division, so we keep the base, and subtract the exponents. So
Result in standard form:
The result in standard form is:
66
Difference means subtract. So, 101-35=66
Answer:
9x + 8
Step-by-step explanation:
2(3x + 1) + 5x + 9 - 2x - 3
⇒ 6x + 2 + 5x + 9 - 2x - 3
⇒ 9x + 8
