Match the attributes to the quadratic functions. x-intercept: (3,0)

x-intercept (1,0)

axis of symmetry: I =

y-intercept: (0,3)

y-intercept: (0,–6)

vertex: (–1,–8)

f(x) = 2x2 + 4x - 6

g(x) = -2x2 + 4x + 3

h(x) = 2x2 - 4x - 6

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

slope is 35 and 20 miles is the y-intercept.
