H(x)=2x-4
g(x)=x^3-3
Find(h+g)(4)

65

Step-by-step explanation:

(h + g)(x)

= h(x) + g(x)

= 2x - 4 + x³ - 3

= x³ + 2x - 7

Then

(h + g)(4)

= 4³ + 2(4) - 7

= 64 + 8 - 7

= 72 - 7

= 65

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

boxplot e is the answer
