First, you would find the area of the rectangle using the formula A = L • W, which would then give you 24 cm2. Then you would find the area of the triangle using the formula A = bh1/2, which would the give you the answer of 8 cm2. Then you would have to find the area of the semi-circle, using the formula A = (r • r) • 3.14 / 2, which would then give you the answer of 25.12 cm2. Finally, you would have to add up all three area’s, so 25.12 + 8 + 24, which would then give you the final answer, which would be 57.12 cm2.

Which graph is the result of reflecting f(x) = (8)x across the y-axis and then across the x-axis?

VARVARA [1.3K]

Refrection of a function across the y-axis, changes the sign of x in the function.

Thus, given the function:
$f(x)=(8)^x$
Refrection of the function across the y-axis will result in the function:
$g(x)=(8)^{-x}$

Refrecting a function across the x-axis, changes the sign of the function.

Thus, refrecting the function:
$g(x)=(8)^{-x}$
across the x-axis will result in the function:
$h(x)=-(8)^{-x}$

The graph of $f(x)=(8)^x$ and $h(x)=-(8)^{-x}$ is attached.
The green curve represents the graph of the function $f(x)=(8)^x$ , while the orange curve represents the graph of the function $h(x)=-(8)^{-x}$ .
