Question

Which function has the greatest x-intercept?

Et
f(x) = 3x - 9
g(x) = (x + 31)
h(x) = 2x – 16
j(x) = -5(x - 2)2

Answer 1

g(x) = (x + 31)

f(x)= 3x-9

3×x-9= -9+3×x

=-6x

g(x)=(x+31)

1×x+31=32+1×x

=32x

h(x)=2x-16

2×x-16= 16+2×x

=18x

j(x)= -5(x-2)2

(-5x+10)2

-10x+20= 10×x+20

=20-10×x

=10x
