The graph of f(x) = (0.5) is replaced by the graph of g(x) = (0.5)* - k. If g(x) is obtained by shifting f(x) down by 3 units, t
Ghella [55]

Answer:

k = 3

Step-by-step explanation:

Given

f(x) = 0.5x

g(x) = 0.5x - k

Required

Find\ k

Initial expression of f(x) is f(x) = 0.5x

From the question; we understand that f(x) was shifted down by 3 units;

This implies that

New\ f(x) = 0.5x - 3

Also from the question; we understand that this new f(x) is equivalent to g(x);

In other words;

New\ f(x) = g(x)

SubstituteNew\ f(x) = 0.5x - 3 and g(x) = 0.5x - k

This gives

0.5x - 3 = 0.5x - k

<em />

Subtract 0.5x to both sides

0.5x - 3 - 0.5x = 0.5x - k - 0.5x

Rearrange

0.5x - 0.5x - 3 = 0.5x  - 0.5x- k

-3 = -k

Multiply both sides by -1

-3 * -1 = -k *-1

3 = k

k = 3
