Given f(x) = -2x^2 + 4, determine the slope of the secant line over the interval [-1, 2].

 -2

Step-by-step explanation:

We know that the slope of a secant line over a interval [a,b] is given by :-

Given f(x) =

Then, the slope of the secant line over the interval [-1, 2] is given by :-

Hence, the slope of the secant line over the interval [-1, 2] is -2.

the answer is 5636.7

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
