Question

the curve y=axsquare+bx passes through(2,0) and (4,8).Find a,b​

Answer 1

Answer:

Correct option is

C

(1/3,1/3)

As it passes through (−1,0), we have

0=a−b

a=b

Also, we have

dx

dy

=2ax+b

2a+b=1

3a=1

a=

3

1

=b

please make as thanks

Answer 2

Step-by-step explanation:

y=ax2 + bx

 

Plug in the two given points, (2,0) and (4,8):

 

0 = a22 + b2 = 4a + 2b

8 = a42 + b4 = 16a + 4b

 

4a + 2b = 0

16a + 4b = 8    (you can reduce this one to 2a + b = 2 by dividing both sides by 4)
