Answer:
y=12x+22 is linear but not proportional
Step-by-step explanation:

This is a linear equation because it has an x and y within the expression without exponents or other complex operators. We can rearrange and simplify the equation into slope-intercept form.

This linear equation follows the form y=mx+b where m is the slope and b is the y-intercept. For this function, m=12 and b=22. This is not a proportional relationship because the function's y-intercept is something other than 0.
x^2 - 49 = 0
Add 49 to both sides:
x^2 = 49
Take the square root of both sides:
X = 7
Answer: No
f(g(x))=1
g(f(x))=2
Because f(g(x)) ≠ g(f(x)) The compositions are not commutative
