Solve for x. 3^(x-1) = 2^(x-4)?
2 AnswersMathematics6 years agosolve for x. 3^(x-1) = 2(x-4)?
1 AnswerMathematics6 years agoGiven the equation 2(x^4) + 4(x^2) + 1 = 0 find all real solutions....?
Intuitively, I can see for any x the value of the function will be positive, and at x = 0 the y value is at its minimum, 1. So there are no real solutions, how can I prove this? I tried substitution (let w = x^2) but the discriminant I keep finding to be positive, which I was hoping to find negative.
