Describe what the vertical line test is used for.

1 answer:

5 0

The vertical line test is used to tell if a graph is a function or not. To pass a vertical line test, you would have to be able to draw a vertical line anywhere on the graph and two points can't be hit. Linear functions will pass the vertical line test, while a horizontal quadratic function will not.

Which equation represents a line that passes through (–9, –3) and has a slope of –6?

brilliants [131]

$\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({{ -9}}\quad ,&{{ -3}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies -6
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-(-3)=-6[x-(-9)]
\\\\\\
y+3=-6(x+9)\implies y+3=-6x-54\implies y=-6x-57$

A company decides to begin making and selling computers. The price function is given as follows: p=−45x+1800, where x is the num

Troyanec [42]

Answer:

Step-by-step explanation:

R(x)=px=x(-45 x+1800)=-45 x²+1800 x

C(x)=7000+100 x

P(x)=R(x)-C(x)=-45 x²+1800 x-(7000+100 x)

or P(x)=-45x²+1800 x-100 x-7000

or P(x)=-45 x²+1700 x-7000
