NEED HELP WITH THESE MATH QUESTIONS, will give 50 points AND CROWN BRAINLIST question 1) Identify the function for f(x)=3 times 1/2^(x-4) +5
Answer options for Q1) Linear, quadratic, or exponential

Question 2) State the parent function of f(x)=3 times 1/2 ^ (x-4) +5
Answer options: f(x)=x^2, f(x)=x, f(x)=1/2^x, f(x)=3^x

question 3 is attached :) thank you!

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
