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
