Question

Write the equation of the quadratic function with roots -1 and -7 and a vertex at (-4, 7)

Answer 1

ok Quadratic equation with 2 roots. as the roots are -1 and -7 it means the factors of this quadratic are (x-(-1)) and (x-(-7)) so (x+1) and (x+7) so you do (x+1)(x+7) =x^2 +8x+7 then check the vertex is at (-4,7) by either sketching it or differentiating to find the minimum/maximum

Answer 2

thank you (;

Answer 3

could you help me with more ?

Answer 4

go for it

Answer 5

Write the equation of the quadratic function with roots -1 and 1 and a vertex at (0, -3).

Answer 6

Write the equation of the quadratic function with roots -10 and -8 and a vertex at (-9, -3)

Answer 7

Write the equation of the quadratic function with roots -2 and 4 and a vertex at (1, 9).

Answer 8

that all (; if thats okay

Answer 9

ok well use wat i did for the first question. the roots are -1 and 1 so factors are (x-(-1)) and (x-(1)). so (x+1) and (x-1) so we do (x+1)(x-1).....which is..
