Identify the vertex, axis of symmetry, the maximum and minimum value, and the domain and range for f(x)=-0.2(x+3)^2-1

according to egenuity the answer is

step-by-step explanation:

d. 344.22

answer: 3 x 2 = 6 and 6+0

step-by-step explanation: sum equals addition and twice is multiplication so its

3 x 2 = 6

6+0= 6

identity property of zero

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.

since the figure has a shape of a trap-ezium, we use the formula, for calculating the area of a trap-ezium to find its area. this formula is given by;

where and are length of the opposite parallel sides and h is the vertical height.

this gives us

square feet
