Answer:

The corresponding point is (1,-4)

Step-by-step explanation:

we know that

The point (1,-8) is on the graph of f(x)

that means

For $x=1, f(1)=-8$

therefore

For the function 1/2f(x)

For $x=1, 1/2f(1)=-8/2=-4$

The corresponding point is (1,-4)

Phantasy [73]

Step-by-step explanation:

$r = \sqrt{ \frac{ax - p}{q + bx} } \\ {r}^{2} = \frac{ax - p}{q + bx}$

r² (q + bx) = ax - p

qr² + bxr² = ax - p

qr² + p = ax - bxr²

qr² + p = x (a - br²)

$x = \frac{q {r}^{2} + p}{a - b {r}^{2} }$

Allisa [31]

Let f(x) = x². Then
y = -f(x) -5

The negative sign in front of f(x) means the graph is reflected across the x-axis. The addition of -5 means the graph is shifted down 5 units.

the 1st selection is an appropriate description.
