Find the axis of symmetry for this parabola:
1 answer:
Answer:
x = - 1
Step-by-step explanation:
The equation of the axis of symmetry for a parabola in standard form
y = ax² + bx + c : a ≠ 0 is found using
x = -
y = - x² - 2x - 5 ← is in standard form
with a = - 1 and b = - 2, thus equation of axis of symmetry is
x = - = - 1
Equation of axis of symmetry is x = - 1

Step-by-step explanation:
Two or more terms are called like terms if they have same variables and powers.
and
are like terms because they have same variable y with same power 2.
and
are not like terms because they have same variable y with different powers.
and
are like terms because they have same variables kt with same power 1.
and
are like terms because both are constant.
and
are not like terms because one have variable and other is constant.
and
are not like terms because they have different variables.
