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

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
