What is wrong with the following equation: 8 + (6/2) = 17 - 5

1 answer:

6 0

8+6/2=17-5

We can start by reducing the fraction using basic division.

Remember, numerator divided by denominator.

6 \ 2 = 3.

Rewrite the equation-

8+3=17-5

It doesn’t matter which side of the equal sign you start with, but in this case I started with the right hand.

8+3= 11

Rewrite-

11=17-5

Now subtract.

17-5=12

Write the equality.

11=12.

This is false.

11≠12.

What is the effect on the graph of the function f(x) = 2^x when f(x) is replaced with f(x − 3)?

mel-nik [20]

Graph of f(x-3) is compressed by a factor of $\frac{1}{8}$ horizontally of f(x).

<u>Step-by-step explanation:</u>

We have, the graph of f(x)= $2^{x}$ , on replacing f(x) by f(x-3) we get:

$f(x-3)$ = $2^{x-3} = \frac{2^{x}}{2^{3}} = \frac{1}{8} 2^{x} = \frac{1}{8} f(x)$ .Below shown are the images for graph of f(x) and f(x-3). Both are functions are exponential , and so having exponential graph but f(x-3) is compressed by a factor of $\frac{1}{8}$ horizontally . Domain and range of both functions are same i.e. F(x) & f(x-3) domain & range are same , just difference in graph : $f(x-3) = \frac{1}{8} f(x)$ .
