Question

HELPPP with number 4

Answer 1

4) 2(8²) + c = 1

2(64) + c = 1

128 + c = 1

c = -127

5) (-4)² + 6(-4) + c = -5

16 - 24 + c = -5

-8 + c = -5

c = 3

6) a(-2)² + c = -10----->4a + c = -10

a(4²) + c = -40----->16a + c = -40

------------------

12a = -30

a = -2.5, c = 0

Answer 2

-127 = c

Explanation:

y = 2x^2 +c

We are given the point (8,1) which means x = 8 and y = 1

1 = 2 ( 8)^2 + c

1 = 2*64 + c

1 = 128+c

Subtract 128 from each side.

1-128 = c

-127 = c
