A quadratic function (f) is given. f(x)=x^2+4x-5 a) Express (f) in standard form
b )Find the vertex as well as the x and y-intercepts of (f)
c) Sketch a graph of (f) clearly labeled
d) Find the minimum OR maximum value of (f)

My assignment is due in less than 24 hrs; any help would be greatly appreciated! ^.^

steps below

Step-by-step explanation:

a) f(x) = (x+2)² - 9

b) y = (x-h)² + k , (h,k) is vertex      vertex (-2 , -9)

   x intercept: (x+2)² - 9 = 0

                       x+2 = ± 3

                       x = 1 or x = -5

   y intercept:  y = -5

c) attached

d) y ≥ -9         [-9,∞)

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope
