(b) x2 + 4x - 3
(c) x2 + 3x - 4

(v) For what value of x'the value of the polynomial (x - 1)2 + 1 is 1?
(b) 0
(c) 1
(d) -2
(a) -1

pls tell fast correct answer = brainliest​

Answer 1

Answer:

(i) b.Parabola

(ii) a.y-axis

(iii) b.5,-2

(iv) b.$x^{2} +4x-3$

(v) c.1

Step-by-step explanation:

• We can see clearly from the graph that the path of football is parabola.
• The axis of parabola is y-axis as t will divide the parabola symmetrically.
• The parabola crosses the x-axis twice, this points are known as the zeroes of parabola.
• The polynomial $x^{2} +4x-3$ has -1 and -3 as its zeroes.
• Putting 1 in the equation $(x-1)^{2}+1$ we get 1 as the result.
