Given that ƒ(x) = 3x, identify the function g(x) shown in the figure.
pogonyaev

We will see that g(x) is a reflection across the y-axis of f(x), then:

   g(x) = f(-x) = 3^{-x\\

<h3>How to identify the function g(x)?</h3>

By looking at the graph, we can see that g(x) is a reflection across the y-axis of f(x).

So we can write:

g(x) = f(-x)

Here we know that:

f(x) = 3^x

Then, replacing f(x) on the formula for g(x), we get:

g(x) = f(-x) = 3^{-x\\

That is the function g(x) shown in the figure.

Find the lengths of the segments with variable expressions
nlexa [21]

Answer:

EF = 7 units

AD =  3 units

BC =  11 units

Step-by-step explanation:

Since it is an isosceles trapezoid and the midsegment is x, the sum of the bases divided by 1/2 is the value of the midsegment, x.

x = 1/2(x-4 + 2x-3)

x = 1/2x - 2 + x - 1 1/2

x = 1 1/2 x - 3.5

-1/2 x = -3.5

x = 7 units

EF = 7 units

AD = 7-4 = 3 units

BC = 2(7) - 3 = 11 units
