Answer:

Based on graph description ...

end behavior: (-∞, +∞), (+∞, -∞)
y-intercept: (0, -4)

Based on what appear to be answer choices ...

end behavior: (-∞, ∞), (+∞, -6)
y-intercept: (0, -5)

Step-by-step explanation:

End behavior

"Starts at top left" means the function approaches +∞ as x approaches -∞.

"Continues decreasing to the bottom right" seems to mean the function approaches -∞ as x approaches +∞.

(While an exponential decay function "continues decreasing", it approaches a limit. Your description of the graph says nothing about that, so we assume it is an odd-degree polynomial function with a negative leading coefficient.)

Y-intercept

"Crosses the y axis at negative 4" means the y-intercept is (0, -4).

Comment on problem statement discrepancies

Perhaps you intended to describe the graph as "approaching -6 at the bottom right." That would match a description, "The graph approaches y = −6 to the right." However, your offered choice of (0, -5) for the y-intercept does not match the verbal description of "crosses the y axis at negative 4."

Virty [35]

A+B)^2 is the largest. It is A^2+2AB+B^2, which is clearly greater than the last two options. To compare (A+B)^2 and 2(A+B), we remove one A+B so that we're just comparing A+B and 2. As A+B must be at least 3 (as both must be positive integers, and one must be greater than the other, leading to a minimum value of A=2, B=1), A+B is greater than 2, and as a result, (A+B)^2 is always the largest.

Hello,

Let x be the number of 14-ounce cans

800-x be the number of bottles

Total weight=14*x+70*(800-x)=14x+56000-70x=56000-56x=56(1000-x)

Someone pls help! write the expression in radical form. 2 4/5

kipiarov [429]

Answer:

$\sqrt[5]{2^4}$

Step-by-step explanation:

Maybe you want 2^(4/5) in radical form.

The denominator of the fractional power is the index of the root. Either the inside or the outside can be raised to the power of the numerator.

$2^{\frac{4}{5}}=\boxed{\sqrt[5]{2^4}=(\sqrt[5]{2})^4}$

In many cases, it is preferred to keep the power inside the radical symbol.
