If f(x) = 2х2 + 3 and g(x) = х2 -7, find (f- а)(x).
а. 3х2 – 4
в. 3х2 – 10
с. х2 – 4
d. х2 + 10

C. x^2 -4

Step-by-step explanation:

What you do is subtract the functions as said by

(f-g)(x).

so:

f(x)-g(x)

(2x^2+3) - (x^2 -7)

2x^2 -x^2 +3 - 7= x^2 -4

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

2425
