Question

which quadratic function, when graphed, has x-intercepts of 4 and -3?

Answer 1

An equation with zeros at 4 and -3.
ie.
\[(x-4)(x+3)\]
If you expand that;
\[x^2-4x+3x-12=x^2-x-12\]

Answer 2

a. y= (x=3)(x+4)
b. y=(x+3)(2x-8)
c. y= (3x-1)(4x+1)
d. y= (3x+1)(8x-2)

Answer 3

Find the zeros of all those. The equation I gave above was one of the infinite possible forms. Any equation with zeros of 4 and -3 would be valid. I would take a look at b.

Answer 4

thank you!

Answer 5

No problem!
