At what point of the curve y = cosh(x does the tangent have slope 2?
Dahasolnce [82]
The hyperbolic cos (cosh) is given by
cosh (x) = (e^x + e^-x) / 2
The slope of a tangent line to a function at a point is given by the derivative of that function at that point.
d/dx [cosh(x)] = d/dx[(e^x + e^-x) / 2] = (e^x - e^-x) / 2 = sinh(x)
Given that the slope is 2, thus
sinh(x) = 2
x = sinh^-1 (2) = 1.444

Therefore, the curve of y = cosh(x) has a slope of 2 at point x = 1.44

PLEASEE HEEELPPPP!!!

Practice proportionality. A 50 difference between 100 and 150 is less relevant than 50 in 25 and 75. Its like you have 1 billion dollars and i give you 10 dollars. Its worthless right? What if you have 20 dollars and i give you again 10 dollars, its half of what you have. See the difference? Same number but different value.

Consider function f.
MariettaO [177]

Answer:

  • x = 2, x = -1, x = -3
  • As x approaches negative infinity, f(x) approaches negative infinity

Step-by-step explanation:

<u>Given function</u>

  • f(x)= x^3 + 2x^2 - 5x - 6

<u>Finding zero's</u>

  • x^3 + 2x^2 - 5x - 6 = 0
  • x^3 - 2x^2 + 4x^2 - 8x +3x - 6 =
  • (x - 2)(x^2 + 4x + 3) =
  • (x - 2)(x^2 + x + 3x + 3) =
  • (x - 2)(x(x + 1) + 3(x + 3)) =
  • (x - 2)(x + 1)(x + 3)

<u>Zero's are</u>

  • x = 2, x = -1, x = -3

<em>See the graph attached</em>

<u>Correct end behavior as per graph:</u>

  • As x approaches negative infinity, f(x) approaches negative infinity
