How can you change the equation y = 2x + 3 to function notation?
qwelly [4]

Answer:

f(x)=2x+3

Step-by-step explanation:

The first thing that would need to be done is solving for y. This problem has already done this. The next step is to exchange y for f(x)

That is all. This would mean that the function notation for the equation would be: f(x)=2x+3

Given b(x) = X+41, what is b(-10)?<br> О -10<br> боооо
ch4aika [34]
Answer: 31
step by step solution: so the function is b(x)=x+41. they want to know what the function would equal when b(-10). so b(-10) means that you would plug (-10) in for x in the function so the function would now be b(x)=(-10)+41. now all you have to do is simplify the function. b(x)=31. so the function b(-10)=x+41 equals 31. hope this helped!!! have a great day.
