Is #y=sqrt(2x-5)# a linear function and explain your reasoning? Algebra Graphs of Linear Equations and Functions Graphs of Linear Equations 1 Answer Gaya3 Oct 5, 2017 No! Explanation: #y=sqrt(2x-5# can be written as #y^2=2x-5# #=y^2color(red)(-y^2)=2x-5color(red)(-y^2# #=2x-5-y^2 = 0#, Whose degree (highest power of the variable) is 2 & is a quadratic function. (Linear function will have degree 1) Answer link Related questions How do you graph # y=4x+7#? How do you graph #p=2(h)#? How many points do you need to plot?
