Question about Quadratics

Question

Explain how you could use (move) f(x)=-x^2+2x+15 to help produce a sketch of g(x)=-(x+4)^2+2(x+4)+10?

Answer 1

1) (x-2i)(x+2i) Multiply it out: x^2 + 2ix - 2ix - 4i^2 Simplify: x^2+4 If you really need a, b, and c in there: y = 1x^2 + 0x + 4 2) [x-(3+i)][x-(3-i)] Multiply it out: x^2 - (3-i)x - (3+i)x + (3+i)(3-i) x^2 - 6x - ix + ix + 9 - 3i + 3i - i^2 Simplify: x^2 - 6x + 9 + 1 x^2 + 6x + 10 y = 1x^2 + 6x + 10

Answer 2

just look in your text book, duh!

Answer 3

Identify the number of solutions to the quadratic equation x² – 7x + 15 = 0

Answer 4

a[1]=3, a[2]=6 and a[n]=3a[n-1]-2a[n-2] find the 3rd 4th and 5th terms

Answer 5

What's the pattern? 3, 11, 23, 39, 59, 83, ...

Answer 6

well if f(x)=-x^2+2x+15 is greater thanf(x)=-x^2+2x+15 than you simply take the mass of the moon and divide that by how mush bigger it is in ration to the mass of the earth in comerason to the sun. which leads you to this equation.  y = 1x^2 + 0x + 4 2) [x-(3+i)][x-(3-i)] Multiply it out: x^2 - (3-i)x - f(x)=-x^2+2x+15 - 3i + 3i - i^2 then just simplify that answer as shown .  Simplify: x^2 - 6x + 9 + 1 x^2 + 6x + 10 y when all is reduces the mass  of the whole galaxy is not small at all and divide that be the size ofthe human brain and if gives you ur answer. 1x^2 + 6x + 10.    it is so simple idk y u would ask for help. hope i shared some of my wisdom!!
