Question

Let f(x) = 8x + 5 and g(x) = -2x - 4 Find the value of f(2) + g(5) *

Answer 1

Answer: lock down

Step-by-step explanation: f(x)= 8x2 + 5=21--> f(x)=21

g(x)= -2x5 - 4=-14--> g(x)=-14

Answer 2

f(2)+g(5) = 7

Explanation:

Given,

f(x) = 8x+5

g(x) = -2x-4

To find f(2)+g(5)

Now,

f(2) means putting the value of x = 2 in f(x)

g(5) means putting the value of x = 5 in g(x)

f(2) = 8(2)+5 = 21

g(5) = -2(5)-4 = -14

Hence,

f(2)+g(5) = 21-14 = 7
