Domain and range of f(x)=sqrt(x^2 -4)

Mathematics

antoniya [11.8K]3 years ago
3 0

Answer:

See explanation

Step-by-step explanation:

The domain of this function is all real numbers, since no matter what x value you input you will get a y value. The range of this function is (-4,\infty), because no matter what x value you input, you cannot go below -4. Hope this helps!

Find the value of r so the line that passes through each pair of points has the given slope.
3241004551 [841]

Answer:

r = 1

Step-by-step explanation:

slope = change in y / change in x, so:

change in y / change in x  = 2/3

5 - r / 7 - 1 = 2/3

5 - r / 6 = 2/3

\frac{5-r}{6}=\frac{2}{3}

now solve this equation.

first, multiply both sides by 6 to get rid of the fraction:

5 - r = 4

subtract 5 from both sides

-r=-1

multiply both sides by -1

r=1

y = 2x - 8

Step-by-step explanation:

Parallel lines have SIMILAR <em>RATE OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so 2 remains the same:

8 = 2[8] + b

↑

16

-8 = b

y = 2x - 8 >> Parallel Equation
