If f(x) equals 3X -2 what is f(5.9)
Ivanshal [37]

Answer:

f(5.9)= 15.7

Step-by-step explanation:

f(x) = 3x -2

f(5.9) = 3(5.9) -2

f(5.9) = 17.7 -2

f(5.9) = 15.7

Word Explination

If the (x) in f(x) is replaced by another variable (in this case, a number) any other x seen in the equation is replaced by that variable. For this question, the x in f(x) is replaced by 5.9. And so any other x in this equation needs to be replaced by 5.9 as well. From there on out, you solve.
