Supposef(0) = 2 and 2 ≤ f '(x) ≤ 7for all x in the interval [−5, 5]. determine the greatest and least possible values of f(2).le

IgorC [24]

If the slope of the function is 2, the amount it can change over the interval 0–2 is

... 2×2 = 4 units

If the slope is 7, the amount it can change over the interval 0–2 is

... 2×7 = 14 units

The least possible value of f(2) is 2+4 = 6.

The greatest possible value of f(2) is 2+14 = 16.

Geometrical prove that limit X tends to zero sin x by X equals to 1 various is measured in radian

11111nata11111 [884]

$lim \frac{ \sin(x) }{x} = 1 \\$

It is true only whenever x tends to 0(zero)

it is not importent that x be in radian or in degree.

(X-3)(x+2)=0 find the zeros

Ivanshal [37]

Answer: Min = (0.5, −6.25)

Step-by-step explanation: Standard form:

x2 − x − 6 = 0

Factorization:

(x + 2)(x − 3) = 0

Solutions based on factorization:

x + 2 = 0 ⇒ x1 = −2

x − 3 = 0 ⇒ x2 = 3
