In order to use a graph to write an equation, you first need to have plot points. Pick 2 points on the line if there isn't already any on the graph. After you find two points, find the slope. (Formula: y = mx + b) After you solve the slope, try finding the y-intercept. (Meaning: when x = 0, solve for y) The y-coordinate when you solve it is the value of "b" in the equation. (REMEMBER: y = mx + b) If you have any questions about the formula or the directions, remember to ask! Cheers, mimiisawesome5
7/9 would be irrational, I think.
No because it does not pass the vertical line test,
meaning that a single vertical line could pass through multiple points on the graph.
110.10 +4x = 150.10
4x=40
x=10 :D
Answer:
The function is "f(x) = 5*x"
Step-by-step explanation:
Everytime we add a number to the independent variable of a function, in this case x, there'll be a common factor between the variable and a pure number. To solve this problem we need to make "(x + 3)" appear. Since we have "f(x+3)" we need to first factor the common denominator. We have:
f(x + 3) = 5*(x + 3)
Therefore,
f(x) = 5*x
