Because you can't solve for two variables at once, you can guess and trial/error.
You can also give x or y any value, and then solve for the opposite variable.

x = 0
y = -36
for example. There are more solutions.

   y + 8 = -4(x+7)
-36 + 8 = -4(0+7)
      -28 = 0 - 28
      -28 = -28

Using the equation y = 3x – 5, what would the output be for an input of 2
Luba_88 [7]

Answer:

Step-by-step explanation:

y = 3x - 5.....input values are x and output values are y

so if ur input (x) is 2.....sub 2 in for x and find ur output (y)

y = 3x - 5

y = 3(2) - 5

y = 6 - 5

y = 1 <=== ur output value

\displaystyle y = Atan(Bx - C) + D

According to this <em>trigonometric function</em>, −C gives you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL.

Extended Information on the trigonometric function

\displaystyle Vertical\:Shift → D \\ Phase\:[Horisontal]\:Shift → \frac{C}{B} \\ Period → \frac{π}{B} \\ Amplitude → |A|

NOTE: Sometimes, your <em>vertical</em><em> </em><em>shift</em><em> </em>might tell you to extend the troughs on each end of your graphs, beyond the <em>midline</em>.

* All tangent functions have NO AMPLITUDES.

I am joyous to assist you anytime.
