Question

Is 3x+y^2=4 a graph of a function??? Please help!!!

Answer 1

Yeah it is!

Answer 2

\( \color{Black}{\Rightarrow y^2 + 3x - 4 = 0}\)

Answer 3

Or am I forgetting my Math?

Answer 4

\( \color{Black}{\Rightarrow y^2 = 4 - 3x}\)

\( \color{Black}{\Rightarrow y = \sqrt{4 - 3x}}\)

Answer 5

Solve for y. A plot of the result is attached.

Answer 6

F(x) = 3x+1,x<=0
x^2,0<x<4,evaluate f(3)
X-5,x>=4

Answer 7

So overall it is a function
