Answer:

f(-2) = 0

Step-by-step explanation:

Given that:

f(x) = bx^2 + 32

f(2) = b(2)^2 + 32

f(2) = 4b + 32

f(2) = 4b = -32

f(2) = b = -32/4

f(2) = b = -8

Thus;

f(-2) = -8(-2)^2 + 32

f(-2) = -8(4) + 32

f(-2) = -32 + 32

f(-2) = 0

I need help with problem
pychu [463]

Answer:

f(x)=4x(x-3)

Vertex=3/2, -9

Step-by-step explanation:

First, factorize it.

That is equal to 4x(x-3)

Therefore, x intercepts are 0 and 3, as  at least one of them need to be 0.

To find the vertex, first find the x of the vertex, which you can do by finding the average of the x intercepts, so it will be 3/2

Then, find the y, by making x in the original equation equal 3/2. This will give us -9 as the y.

The vertex will by 3/2, -9

The bar graph in the following graphic represents fictional net exports in billions of dollars for five countries. Net exports a
harina [27]

Answer:

$80 billion

Step-by-step explanation:

From the graph, we have the following:

United\ States = -110

Denmark = -30

China = 120

Germany = 40

Spain = 30

Required

Determine the difference in US and Denmark exports

The difference is calculated as thus:

Difference = Denmark - United\ States

This gives:

Difference = -30 - (-110)

Difference = -30 +110

Difference = 80

<em>Hence, the difference is $80 billion</em>

avanturin [10]
Umm this might be wrong, but i think you have do the inverse, which would make -4 positive, then add that to the 2, and then subtract that from 0.6  and then whatever you answer you get is equal to the variable z.
