Write the linear equation that gives the rule for this table.

Maksim231197 [3]

to get the equation of any straight line all we need is two points, well, let's just grab them from the table.

hmmm let's use (-49 , -39) and hmmm say (67 , 77)

$(\stackrel{x_1}{-49}~,~\stackrel{y_1}{-39})\qquad (\stackrel{x_2}{67}~,~\stackrel{y_2}{77}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{77}-\stackrel{y1}{(-39)}}}{\underset{run} {\underset{x_2}{67}-\underset{x_1}{(-49)}}}\implies \cfrac{77+39}{67+49}\implies \cfrac{116}{116}\implies 1$

$\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-39)}=\stackrel{m}{1}(x-\stackrel{x_1}{(-49)}) \\\\\\ y+39=1(x+49)\implies y+39=x+49\implies y=x+10$

Use the inverse of the function y = x2 − 18x to find the unknown values.

Lerok [7]

ANSWER

b=1, c=81, and d=9.

EXPLANATION

The given function is:

$y={x}^{2}-18x$

This function is the same as:

$y={(x - 9)}^{2}-81$

To find the inverse of this function, we interchange x and y.

$x={(y-9)}^{2}-81$

Solve for y:

$x+81={(y- 9)}^{2}$

Take square root of both sides:

$\pm \sqrt{x + 81}=y-9$

$y=\pm \sqrt{x + 81}+9$

Hence,

b=1, c=81, and d=9.
