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).

Molodets [167]

Answer:

3²

Step-by-step explanation:

Given expression:

\sf (3^{-3} \div 3^{-10}) \times 3^{-5}

Following the <u>order of operations</u>, carry out the calculations inside the parentheses first.

\textsf{Apply the quotient exponent rule} \quad a^b \div a^c=a^{b-c}:

\implies \sf 3^{-3-(-10)} \times 3^{-5}

\implies \sf 3^{-3+10} \times 3^{-5}

\implies \sf 3^{7} \times 3^{-5}

\textsf{Apply the product exponent rule} \quad a^b \times a^c=a^{b+c}:

\sf \implies 3^{7+(-5)}

\sf \implies 3^{7-5}

\sf \implies 3^2

James drove up 6,400 feet to a camp area on a mountain to meet his friends. They walked a trail that led to the mountain summit
gregori [183]
The answer is 4900 because you add the 6,400+1,800=8,200 then you subtract the 8,200-3,300= 4,900

LiRa [457]

Answer:

x = 15°

Step-by-step explanation:

Complementary angles are two angles whose sum = 90°

∠A + ∠B = 90°

3x + 45 = 90

3x = 45

x = 45/3

x = 15°
