Is the relation in this set of points a function

It is not a function—an element from the domain is paired with more than one element from the range. Specifically, the input value of 4 corresponds to two output values: 5 and -4.

A function can only take on one output for each input. It only takes one input value to associate with more than one output value to be invalid as a function.

The line y=15x Intersex the quadratic function y=15x^2 at two points. what are the coordinates of the two points of intersection

REY [17]

Answer:

D

Step-by-step explanation:

we can set up the equation as 15x = 15x^2

factoring we get

15x(x-1) = 0

So the solutions are when x are 0 and 1

this gives the coordinates

(0,0) and (1,15)

Write the following in point-slope form using the given information: Slope: 2 points

SCORPION-xisa [38]

Answer:

$y+5 = \frac{1}{15}(x - 3)}$

Step-by-step explanation:

Given

$m = \frac{1}{15}$ -- Slope

$(x_1,y_1) = (3,-5)$ --- Point

Required

Write an equation in point slope form

The point slope form of an equation is:

$y - y_1 = m(x - x_1)$

Substitute values for y1, x1 and m

$y-(-5) = \frac{1}{15}(x - 3)}$

$y+5 = \frac{1}{15}(x - 3)}$

Hence, the equation in point slope form is:

$y+5 = \frac{1}{15}(x - 3)}$

What is the equation of the line that passes through the point (-2,7) and has a slope of zero

Lina20 [59]

Answer:

Equation of the line that passes through the point (-2,7) and has a slope of zero is given as

$y=7$

Step-by-step explanation:

Equation of line is given as

$y-y_1=m(x-x_1)$ -----------(1)

Here

$m=0 \ \ \ and \ \ \ (x_1, y_1) = (-2, 7)$

Substituting values in equation (1)

$y-7=0(x+2)\\y=7$
