Given the function f(x) = 2-4, determine the slope of the tangent line of f at

AlladinOne [14]

Answer:

Slope of the tangent line at x=-1

$(\frac{dy}{dx})_{x=-1} = e^{-5}$

Step-by-step explanation:

Explanation:-

Given function

y = f(x) = e ˣ⁻⁴ ...(i)

Differentiating equation (i) with respective to 'x' , we get

$\frac{dy}{dx} = e^{x-4} \frac{d}{dx} (x-4)$

$\frac{dy}{dx} = e^{x-4} (1)$

Slope of the tangent line

$(\frac{dy}{dx})_{x=-1} = e^{-1-4} = e^{-5}$

Compare fraction 2over 3 and 7 over 8 which is greater

Paul [167]

If you use a calculator to find the exact decimal of these fractions, you can easily find this out.

2/3 as a decimal equals: 0.6666 (repeating sixes)

7/8 as a decimal equals: 0.875

0.875 > 0.666

7/8 > 2/3

7 over 8 is greater! Hope this helps! :)

Doss [256]

Answer:

8x² + 6x - 35

Step-by-step explanation:

A = (2x + 5)(4x - 7)

Front: 2x * 4x = 8x²

Outside: 2x * (-7) = -14x

Inside: 5 * 4x = 20x
