It helps if you have an example, like f(x) = 2x+3
What you typically do, is:
- draw xy axis, label them (ie., 1,2,3,4 along both axes)
- calculate the f(x) values for several x (e.g., -2, 0, 1, 3, doesn't matter).
- plot the calculated values as points. The calculated f(x) is your y value.
- sketch a smooth line through the points. It helps if you know in advance if the line is going to be straight or curved.
- The more points you calculate, the more accurate your graph will be
Answer:
27
Step-by-step explanation:
If we follow the amount of players called,
Coach called three/3
Players called three/3
Three players called three/3
And make it into a equation, 1 x 3 = 3
Those three people call three more: 3 x 3 = 9
Those nine people call three more: 9 x 3 = 27
At 7 pm, the temperature was 66*F
Temp = 78 - 3x where x = number of hours
78 - 3(7-3)
78 - 12 = 66
Answer:
2x^2
Step-by-step explanation:
2x*1x= 2x^2
Answer:
B
Hope this helps!
explanation:
we solve the inequality and to do that we must first subtract 12 from both sides, which gets us -x<-4, then we divide both sides by -1, which gives us x>4, since we have to flip the sign when we divide by a negative. when we graph this, there will be a circle around 4 and the arrow pointing to the right, since it's greater than.
