A Linear Equation is Always a Function
Yes, all linear equations are functions, because the each equation has only one answer at a time.
No. A linear equation is always a function. Y = 3x +4 can only be one answer at a time. It can change by what ever x or y is substituted with, but it can’t have to outcomes with one substitution.
(Is this RIGHT)
f(x) = 12x + 15
f(x) = 12(12) + 15
(x) = 144 +15 = 159
Can you provide another example please?
Same with this one can you help?
F (x) = x² + 2
X = 2
X = 3.
