Question

Illustrate the graph of the given one-to-one

1. f(x)=3x-4 2. f(x) = 5x+3

3. f(x)=7x-5

4. f(x)=1-2

5. f(x)=123

6. f(x)=x+5

Answer 1

1. $f(x)=3x-4$

2. $f(x) = 5x+3$

3.$f(x)=7x-5$

4. $f(x)=1-2$

$f(x)=-1$

The function $f(x)=1-2$ is not a one-to-one function

$$f(0)=-1=f(1), 0\not=1$$

5. $f(x)=123$

The function $f(x)=123$ is not a one-to-one function

$$f(0)=123=f(1), 0\not=1$$

6. $f(x)=x+5$
