Use the four-step process to find f'(x) and then find f'(1), f'(2), and f'(3).

Soloha48 [4]

Step 1: evaluate f(x+h) and f(x)

We have

$f(x+h) = -(x+h)^2+6(x+h)-5 = -(x^2+2xh+h^2)+6x+6h-5$

$= -x^2-2xh-h^2+6x+6h-5$

And, of course,

$f(x)=-x^2+6x-5$

Step 2: evaluate f(x+h)-f(x)

$f(x+h)-f(x)=-x^2-2xh-h^2+6x+6h-5-(-x^2+6x-5)=-2xh-h^2+6h$

Step 3: evaluate (f(x+h)-f(x))/h

$\dfrac{f(x+h)-f(x)}{h}=-2x-h+6$

Step 4: evaluate the limit of step 3 as h->0

$f'(x) = \displaystyle \lim_{h\to 0} \dfrac{f(x+h)-f(x)}{h}=-2x+6$

So, we have

$f'(1) = -2\cdot 1+6 = 4,\quad f'(2) = -2\cdot 2+6 = 2,\quad f'(3) = -2\cdot 3+6 = 0$

How do you solve the equation<br> x-2y-1=0<br> y-5x+14=0

Tcecarenko [31]

The solution is x= 3 and y = 1

Step-by-step explanation:

Given equations are:

$x-2y-1 = 0\ \ \ \ Eqn1\\y-5x+14 = 0\ \ \ \ Eqn2$

From equation 1:

$x = 2y+1$

Putting in equation 2:

$y - 5(2y+1)+14 = 0\\y-10y-5 +14 = 0\\-9y-5+14 = 0\\-9y+9 = 0\\-9y+9-9 = 0-9\\-9y = -9$

Dividing both sides by -9

$\frac{-9y}{-9} = \frac{-9}{-9}\\y = 1$

Putting y = 1 in equation 1:

$x - 2(1)-1 = 0\\x -2-1 = \\x-3 = 0\\x-3+3 = 0+3\\x = 3$

Hence,

The solution is x= 3 and y = 1
