Question

You compared the two functions below. f(x) = 1.2t      g(x) = 1.2t-5

Answer 1

Answer:

B. It shifts the graph of f right 5 units.

F. It divides all the y-values by 1.25.

Step-by-step explanation:

Let me revise your two functions:

f(x) = $1.2^{t}$

g(x) = $1.2^{t-5}$

So g(x) is the transformed function of f(x), as we know that

• if we subtract anything from x or t (independent variable), the graph will move right.

• if we add anything from x or t (independent variable), the graph will move left.

In this situation, we subtract 5 from it, so the graph of f right 5 units.

However, it also affect to the value of y, I will rewrite g(x)

g(x) = $\frac{1.2^{t} }{1.2^{5} }$ = $1.2^{t}$ *$\frac{1}{1.25^{5} }$ = $\frac{1}{1.25^{5} }$ f(x)

Answer 2

The second and the last are the correct ones
