zeros of quadratic function?

Question

. Find the zeros of the function f(x) = x + 3 - 5to the sqrt of x + 3 - ( 4)

2. Find k if f(x) = x^2 +2x + k doesn't intersect the x -axis

Answer 1

4--4k<0 so k>1
1)x+3-5^(x+3)-4
x+3 = z
z-5^z/5^4=0 This can´t be solved by elementary(algebraic means)
Write your first question clearly

Answer 2

For question 1, it would be of great help if you could specify the equation more clearly.

With question 2, as long as k > 1, the function will not have any real zeros.

Answer 3

clear the question
k must be greater than 1
