Answer: h(x)
Explanation:
1) f(x) is not a function because there is an ambiguity for x = 4.
x = 4 belongs to both intervals - 2 ≤ x ≤ 4 and x ≥ 4
Then you find two different possible images for x: 0 and -(2)^2 = - 4.
That makes that f(x) be not a function.
2) similar thing happens with g(x)
as per the given relation the value of g(x) for x = 2 is 4 and 4+1 = 5. Which makes that g(x) be not a function.
3) j(x) is not a function because the image of x = -4 is -3(-4) = 12 and 3.
4) h(x) is a function, because there is not any ambiguity in its definition, for every x in its domain there is only one image h(x).
The answer to your Question is 8/10 but if you simplify it the answer is 4/5.
<u><em>Answer is in bold</em></u>
Harry can first substitute 30 for t. He can then multiply 
by 30 to get a product of 10. Since 15 is equal to 30 × 1/2, Harry's solution is not correct.
Hope this helps :)
Have a great day!
