URGENT! Complete the equation describing how ex and Y related! Help on the last part please!

Mathematics
1 answer:
Nikolay [14]4 years ago
7 0

Answer:

y = - 0.5x - 1

Step-by-step explanation:

The equation is of the form

y = mx + c ( m is the slope and c the y- intercept )

m = - 0.5 is already given as y = - 0.5x

Using the ordered pair (0, - 1 ) ⇒ c = - 1

Thus

y = - 0.5x - 1 ← is the equation

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
