REC(x) = 1

Mathematics
1 answer:
Nastasia [14]4 years ago
4 0

Answer: a. 8; 1/2

Step-by-step explanation:

a. if the function is f(x)=2x+3 and they ask you what is f(5)? Then you just replace x with what they replaced x with and solve. f(5)=2(5)+3. 2x5=10+3=13 so then f(5)=13. So in your case they replace x with 2. Plug it in. h(2)=2^2+4.

2 to the power of 2 is 4 and then + another 4 which is 8. Thats how you get the first one, now you try and solve REC(2).
