If an equation of the tangent line to the curve y=f(x) at the point where a = 2 is y=4x-5 find f(2) and f'(2)

vichka [17]

hello :
at the point where a=2 y = 4(2)-5 =3 (commun the curve and the tangent)
so :f(2) = 3
f'(2) =4 (slope of the tangent )

Rewrite each equation in vertex form by completing the square. Then identify the vertex.

ioda

ANSWER

Vertex form;

$y = 3( {x + \frac{3}{2} })^{2} - \frac{35}{4}$

Vertex

$V( - \frac{3}{2} , - \frac{35}{4} )$

EXPLANATION

Given:

$f(x) = 3 {x}^{2} + 9x - 2$

We complete the square as follows:

$y = 3( {x}^{2} + 3x) - 2$

$y = 3( {x}^{2} + 3x + \frac{9}{4} ) - 2 - 3 \times \frac{9}{4}$

The vertex form is:

$y = 3( {x + \frac{3}{2} })^{2} - \frac{35}{4}$

The vertex is

$V( - \frac{3}{2} , - \frac{35}{4} )$

Step-by-step explanation:

midpoint of segment: (x , y) : ((x + x') / 2 , (y + y') /2)

x = (3 + (-6)) / 2 = -3/2

y = (5 + 1) / 2 = 3
