X squared -8x+14=2x-7

Stella [2.4K]

Answer:

x = 3 or x = 7

Step-by-step explanation:

X² - 8x + 14 = 2x - 7

x² - 8x + 14 - 2x + 7 = 0

Now we have a quadratic equation ;

x² - 10x + 21 = 0

-3 and - 7 gives a sum of - 10 and a product of 21

x² - 3x - 7x + 21 = 0

x(x - 3) - 7(x - 3) = 0

(x - 3) = 0 or (x - 7) = 0

x = 3 or x = 7

What are the domain and range of f(x)=[1/5]x

Ber [7]

Answer:

Domain: All real numbers

$(-\infty,+\infty)$

Range: All real numbers

$(-\infty,+\infty)$

Step-by-step explanation:

The given function is $f(x)=\frac{1}{5}x$

This a polynomial function of degree 1.

Polynomial functions are continuous everywhere.

The function is therefore defined for all real values of $x$ .

The domain is $(-\infty,+\infty)$

If we let $y=\frac{x}{5}$

Then, $x=5y$ .

$x$ is also defined for all real values of $y$ , hence the range is also all real numbers or $(-\infty,+\infty)$
