Question

Quick Help please
I don’t understand please answer all four

Answer 1

1) f(-3)

= 2x + 5

= 2×(-3) +5

= -6+5

= -1

2) g(x)- h(x)

= -3x² + 2x - 6 -(-4 - x)

= -3x² + 2x - 6 + 4 + x

= -3x² + 3x - 2

3) f(x) = h(x)

or, 2x + 5 = -4 - x

or, 2x + x = -4 - 5

or, 3x = -9

or, x = -9/3

or, x = -3

4) i am not sure about the last but the answer is between f(x) and h(x). But i think its f(x).
