SOLUTION: I have to graph the following functions:
f(x)= -3x +7
f(x)= -3x (squared) + x - 5
This is what I have thus far. Can someone help me?
f(x) - -3x + 7
y = -3x + 7
-3x + 7

Question 145855: I have to graph the following functions:
f(x)= -3x +7
f(x)= -3x (squared) + x - 5
This is what I have thus far. Can someone help me?
f(x) - -3x + 7
y = -3x + 7
-3x + 7-7 = 0-7
-3x/3 = -7/3 or -2 1/3
**I don't know where to go from here.....
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
graph the following functions:
f(x)= -3x +7
You need two points to graph a line:
Let x = 0, then y = 7
Let x = 1, then y = 4
-------
Plot the points (0,7) and (1,4)
Draw a line thru them to get:
===========================
f(x)= -3x^2 + x - 5
You need three points to graph a parabola:
Let x = 0, then y = -5
Let x = 1, then y = -7
Let x = -1, then y = -9
---
Plot the three points and draw a parabola thru them opeing downward:
=====================
