Answer:

d

Step-by-step explanation:

The red graph is an enlargement of the black graph.

Note coordinates of vertices of black graph to coordinates of red graph

(2, 2 ) → (2, 4 )

(4, - 2 ) → (4, - 4 )

(- 2, - 2 ) → (- 2, - 4 )

The y- coordinates of the red graph are twice the y- coordinates of the black graph.

and

\frac{y}{2} = f(x) ← multiply both sides by 2

y = 2f(x) ← as required, thus

equation of red graph is

\frac{y}{2} = f(x) → d

Answer:

x = 3.5

Step-by-step explanation:

Triangle to the right:

4^2 + x^2 = 8^2

16 + x^2 = 64

y^2 = 48

Triangle to the left:

x^2 + 6^2 = 48

x^2 + 36 = 48

x^2 = 12

x = sqrt(12)

x = 3.5
