Question

Nellie is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect?

Answer 1

Answer: yes choice B

Explanation:

g(x) has -5 slope

y - g(-1) = -5(x +1)

y -5 = -5x -5

y = -5x

f(x) = xx/2 +2

Xx/2 +2= -5x

Xx/2 +5x +2 = 0

Xx + 10x +4 =0

Solutions: -5 + root(100 -16)/2

And -5 - root(84)/2

Both intersection look like in negative x values
