Question

Given  f(x)=2x+4 and g(x)=x2−4, determine the value of (5) + (−3).

Answer 1

Answer:

c 41

Step-by-step explanation:

Substitute 5 in and it is 2^5 not 2*5 so that would be 32 not 10 and then just

add and subtract and multiply the rest and it's 41

Answer 2

Answer:

None of the above, f(5) + g(-3) = 19.

Step-by-step explanation:

Given f(x)=2x+4 and g(x)=x2−4, determine the value of (5) + (−3). Assume that is supposed to be f(5) + g(-3).

f(5) + g(-3) = 2×5 + 4 + (-3)^2 - 4

= 10 + 4 - 4 + (-1)^2(3)^2

= 19
