What transformation has changed the parent function f(x) = log3x to its new appearance shown in the graph below?
Wittaler [7]

Answer : option B

Parent Graph f(x) = log_3(x) is attached below

We analyze each option

A) f(x − 2) --> x - 2 shifts the graph 2 units to the right

B) f(x + 2) --> x + 2 shifts the graph 2 units to the left

C) f(x) − 2 --> f(x) - 2 shifts the graph 2 units down

D) f(x) + 2 --> f(x) + 2 shifts the graph 2 units up

In the graph of f(x)= log_3(x) , the x intercept at x=1

From the graph attached in the question, the x intercept at x=-1

Its means the parent graph is shifted 2 units to the left.

Option B: f(x + 2) --> x + 2 shifts the graph 2 units to the left

Blairs new computer cost 5$ less than twice the cost og her old computer. Her new computer cost 709$. how much did blairs old co
Phantasy [73]

The cost of old computer is $ 357

<em><u>Solution:</u></em>

Let "x" be the cost of old computer

From given,

Cost of new computer = $ 709

Blairs new computer cost 5$ less than twice the cost of her old computer

Therefore,

Cost of new computer = twice the cost of old computer - 5

Cost of new computer = 2x - 5

709 = 2x - 5

2x = 709 + 5

2x = 714

Divide both sides by 2

x = 357

Thus the cost of old computer is $ 357
