What is the vertex of the quadratic function f(x)=(x-8)(x-2)

1 answer:

7 0

F(x)=(x−8)(x−2)

y=(x−5)2−9
(Pretend the 2 is an exponent)

Use the vertex form, y=a(x−h)2+ky=a(x-2+k, to determine the values of a,h, and k.

a=1
h=5
k=-9

Find the vertex (h, k).
(5, -9)

Alexus [3.1K]

Answer:

To get an expression relating to x you need to have x alone on one side of your equation. ie x =

Try this:

rx - st = r

remove st from the rx side

rx = r + st

now divide by r

x = (r + st)/r

You now have your expression relating to x

Don tracked the price of gas for several months. In January gas cost $2.65, in February the price had risen $0.56, in March decr

Elan Coil [88]

Starting price is 2.65, increased by .56

2.65+.56=3.21

Price is 3.21, decreased by .23

3.21-.23=2.98

Price is 2.98, increased by 1.02

2.98+1.02= 4

Price is 4, decreased by .48

4-.48=3.52

Now find the difference from the starting price (January) from the end price (May)

3.52-2.65=.87

<u>The difference from gas prices is $.87</u>
