for the function f(x) = -(x + 1)2 + 4, identify the vertex, domain, and range. (2 points)

The vertex is the point (-1,4)

The domain is the interval (-∞,∞)

The range is the interval  (-∞,4]

Step-by-step explanation:

we have

This is the equation of a vertical parabola written in vertex form

The parabola open downward (because the leading coefficient is negative)

The vertex represent a maximum

The vertex is the point (-1,4)

The domain is the interval (-∞,∞)

The domain is all real numbers

The range is the interval  (-∞,4]

The range is all real numbers less than or equal to 4

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
