Ответ:
h(x) = 3x(x - 2) - 4 = 3x^2 - 6x - 4 is a quadratic function.
Ответ:
h(x) = 3x(x – 2) – 4
Step-by-step explanation:
p(x) = 2x(x^2 + 6) + 1
Multiply 2x inside the parenthesis
p(x)= 2x^3 +12x (It is a cubic function)
m(x) = –4(x + 3) – 2
Multiply -4 inside the parenthesis
m(x)= -4x -12 -2 (It is a linear function)
t(x) = –8x^2(x^2 – 6) + 1
multiply -8x^2 inside the parenthesis
t(x)= -8x^4 +48x^2 +1 (Its is not quadratic because highest exponent is x^4)
h(x) = 3x(x – 2) – 4
Multiply 3x inside the parenthesis
h(x)= 3x^2 -6x -4 (It is a quadratic function because highest exponent is x^2)
