Answer :

Answer:

1) 3

2)-2

3)-29.75

4) 121

5)-11/4

6)176/5

Step-by-step explanation:

I got u

so when you have something like f(x) and f(2), what it really means is what is the answer if I plugged in x as 2 in the function f(x), well lets find out.

f(2) = 2^2 + 7 = 4+7 = 11

Same thing for g(-3), what would be the answer if I plugged in x = -3 in the function g(x)

g(-3) = 3(-3) +2 = -7

Now each number just makes an equation out of these rules, so what is f(2) + g(-3), well we just calculated each of the value so 11-7 = 3

Im sure you can do 2, it is the same. Answer: -2

No.3 nothing to be scared, just replace f(x) x by a fraction. Answer:-29.75

No.4 You got this! just do the same rule, but multiply by each other. Answer: 121

No.5 Just divide by each other. Answer:-11/4

No.6 looks harder so I'll be nice and do it for you

so we have two f(x) values to calculate

f(5) = 5^2 + 7 = 25+7 = 32

f(3) = 3^2 + 7 = 9+7 = 16

now we have 1 g(x) value to calcualte

g(1) = 3(1) + 2 = 5

Now lets replace each f(x) and g(x) by our calculated value

32 + 16/5

You know how to add fractions

(32*5 + 16)/5 = 176/5

Hope that answers your question
