Answer:
y = (x + 1)²
Step-by-step explanation:
y = 1 + x² + 2x
⇒ x² + 2x + 1 = y
⇒ (x + 1)(x + 1) = y
⇒ (x + 1)² = y
y-intercept when x = 0:
(0 + 1)² = 1² = 1
Therefore, intercepts the y-axis at (0, 1)
x-intercept when y = 0
(x + 1)² = 0
x + 1 = 0
x = -1
Therefore, intercepts (touches) x-axis at (-1, 0)
Answer:
Step-by-step explanation:
The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve
1 meter = 3.2808 feet
1 x 1 x 1 cubic meter = 3.2808 x 3.2808 x 3.2808 cubic feet
1 cubic meter = 35.3134 cubic feet
9 cubic meters = 35.3134 x 9 = 317.8 cubic feet.
The answer is c i’m pretty sure
