question is Use fzero to find the largest x-value where ex+1 meets cos(5x). Use a nearby sensible integer value of your choice.

Code that I have: fzero('exp^(x+1)==cos(5*x)',10)

error: Error using fzero (line 289) FZERO cannot continue because user-supplied expression ==> exp^(x+1)==cos(5*x) failed with the error below.

 Error in inline expression ==> exp^(x+1)==cos(5*x)
 Not enough input arguments.

Error in project1 (line 31) p16=fzero('exp^(x+1)==cos(5*x)',10)

Bradley, use

 sol = fzero(@(x) exp(x+1)-cos(5*x),10)
 sol =
