Answer:

Graph D

Step-by-step explanation:

$f(x)= 2^x$

Given f(x) is a exponential function

The graph (a) is a graph of an absolute function because we have V shaped graph

The graph (b) is the graph of a line so it is a graph of a linear function

The graph (c) is a U shaped graph. U shaped graph is a graph of a quadratic function.

The graph (d) is a curve shaped graph. It is a graph of an exponential function.

A. Sam purchased 3 games for $140 after a discount of 30%. What was the original price?

Semmy [17]

Answer:

a) $175 b) It will be $126

Step-by-step explanation:

Cost price of 3 games= $140

Let the original price of games= $ x

Discount is given= 30%

According to question

x $\frac{(100-20)}{100}$ = $140

x $\frac{80}{100}$ = $140

x ×0.8= $140

x= $ $\frac{$140}{0.8}$

x= $175

Hence, the original price of games $ 140

(b) If Sam had given a discount of 20%

Again a discount = 10%

The price of games=$ 140

Now, the selling price will be= 175 $\frac{(100-20)}{100}$ × $\frac{(100-10)}{100}$

Now, the selling price will be= $ 126

Hence, the price will be different.
