According to one of the properties of powers of the same base, we must put the same base and add the exponents:
Answer:
Option B
Simplify this quadratic function given in vertex form into standard form by simplifying the exponents and adding like terms.
(good luck :) and mark me brainliest if you're satisfied with my answer)
Answer:
see explanation
Step-by-step explanation:
1
The cosine function in standard form is
y = acos(bx + c)
where a is the amplitude, period = and
phase shift = -
here b = 2 and c = , thus
phase shift = - = -
2
the amplitude = | a |
which has a maximum of a and a minimum of - a
y = 4cosx ← has a maximum value of 4
