Which equation can be simplified to find the inverse of y = 2x2?

irakobra [83]

Given:

$y=2x^2$

To find:

The equation that can be simplified to find the inverse of given equation.

Solution:

We have,

$y=2x^2$

To find the inverse first we have to interchange x and y.

$x=2y^2$

Now, we to solve this equation for y to find the inverse.

So, the equation $x=2y^2$ can be simplified to find the inverse of given equation.

Therefore, the correct option is 4.

The function shown in the graph is

pshichka [43]

Answer:

Linear function

y = 2x - 1

Step-by-step explanation:

This is a linear function because the line is straight, having no curved.

The equation for a linear graph is y=mx + b.

x and y represent points on he graph.

"m" represents the slope of the graph. Reading from left to right, if a positive slope, then the graph continues upward. If negative, then it's a graph down downwards.

"b" represents the y-intercept, when the graph hits the y-axis. It's also the initial value.

In the photo, we can see the y-intercept is (0, -1).

Slope is calculated by rise over run. Choose two random points on the graph. Count the "rise", or how many vertical units are between the points. If the point on the right is lower than the point on the left, the rise is negative. Count the "run", which is the number of horizontal units between the points.

For the point (0, -1) and (3, 5).

m = rise/run

m = 6/3

m = 2

Substitute m=2 and b= -1 into the equation of a line.

y = 2x - 1

The rational function has a y-intercept of 7. What is the equation for this function?

Schach [20]

Answer:

$\large\boxed{f(x)=\dfrac{4}{x+2}+5}$

Step-by-step explanation:

$f(x)=\dfrac{a}{x-b}+c\\\\\text{We have}\\\text{(1) the vertical asymptote}\ x=-2.\ \text{Therefore}\ b=-2.\\\text{(2) the horizontal asymptote}\ y=5.\ \text{Therefore}\ c=5.\\\text{(3) the point (0, 7). Put the coordinates of the point to the equation}\\\text{of the function}\\y=\dfrac{a}{x-(-2)}+5\\\\7=\dfrac{a}{0+2}+5\qquad\text{subtract 5 from both sides}\\\\2=\dfrac{a}{2}\qquad\text{multiply both sides by 2}\\\\4=a\to a=4\\\\\text{Finally:}\\\\f(x)=\dfrac{4}{x+2}+5$
