Which function has an inverse thats is also a function?

The measurement of one angle of a right triangle is 34°. what is the measurement of the third angle?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined
