Answer:
A linear function is an equation that is set equal to f(x) and creates a straight line when graphed. Typically this is written as f(x) = mx + b or the slope-intercept form. Linear equations also include: Point-slope form: y − y 1 = m ( x − x 1 )
Step-by-step explanation:
Here are some more examples. Let's say you're given the value of x. You can solve for f(x) in the same way. Just follow the steps to isolate the unknown f(x).
If f(x) = 5x - 1, what is f(2)? Here, we are told that x = 2 by the substitution of 2 in the function format f(x).
Step 1
Substitute. So:
f(x) = 5(2) - 1
Step 2
Isolate the variable. Here, the variable of f(x) was already isolated, so we can move to simplifying. So:
f(x) = 10 - 1
Step 3
Simplify. So:
f(x) = 9
