Question

Which values complete the function?

Answer 1

f(x)=-1(x+4)(x-3)

or f(x)=-(x+4)(x-3)

Explanation:

We see zeros at x=-4 and x=3.

So the factors are (x+4) and (x-3).

So we have a function that looks like

f(x)=A(x+4)(x-3).

y=A(x+4)(x-3)

I see the point (1,10) is on the curve.

So that means

10=A(1+4)(1-3)

10=A(5)(-2)

10=A(-10)

A=-1

So the function is f(x)=-1(x+4)(x-3)

or f(x)=-(x+4)(x-3)
