Does the equation x2 - 4x + y2 = -3 intersect the y-axis?

1 answer:

6 0

No. The y-intercept is the value of y when x=0, hence it intersects the y-axis when x=0. In this case:

0^2-4(0)+y^2=-3

y^2=-3

y=√-3

Since there is no real square root of a negative value, the curve does not intersect the y-axis

if (20,14) is an ordered pair of the inverse of f(x) which of the following is an ordered pair of the function f(x)

Strike441 [17]

<h3>(14, 20) is the ordered pair of the function f(x)</h3>

<em><u>Solution:</u></em>

Given that,

(20, 14) is an ordered pair of the inverse of f(x)

We have to find the ordered pair of the function f(x)

In an inverse funciton, the domain of f(x) becomes the range and range of f(x) becomes the domain

To find the ordered pair of the function f(x), we swap the variables x and y

(y, x) of inverse of f(x) becomes (x, y) of f(x)

Therefore, (14, 20) is the ordered pair of the function f(x)

Answer: x= 2.5, y = 10

Step-by-step explanation:

<u><em>I'm going to assume that these photocopies are proportional in relations to each other.</em></u>

If they're proportional, you can set up two proportions:

$1) \frac{x}{5} =\frac{3}{6} \\\\2) \frac{5}{y} =\frac{3}{6}$

And cross-multiply:

$1) 6x = 5*3 \\\\2) 3y = 5*6$

Then solved for x and y:

$1) 6x = 15\\x=\frac{15}{6} =\frac{5}{2} =2.5 \\\\2) 3y = 30\\y=\frac{30}{3} =10$

I seef(x) between 0 to 1 is goes to xfinity but in the negative direction
We can say it is large neagtive numbet when x is between 0 and 1
