Question

Will fan and medal!

Identify the maximum or minimum value and the domain and range of the graph of the function

y = 2(x + 2)2 - 3

A.
minimum value: 3
domain: all real numbers 3
range: all real numbers


B.
maximum value: -3
domain: all real numbers ≤ 3
range: all real numbers



C.
maximum value: 3
domain: all real numbers
range: all real numbers ≤ 3


D.
minimum value: 3
domain: all real numbers
range: all real numbers ≥ -3

Answer 1

the domain is the set of x values that will satisfy the function
the range is the set of the lowest y value to the highest y value

Answer 2

the minimum value for y is -3 when x = -2
x^2 is always positive
