Question

If p(x)=5(x²+1)+16 then what is p(11)?

Answer 1

Answer:

626

Step-by-step explanation:

1. substitute whatever they put in the brackets into wherever X appears in the equation
2. they put 11 in the brackets, so replace X in the equation with 11
3. $5({11}^{2} + 1) + 16$
4. this is just 5 (121+1) + 16
5. 5(122) + 16
6. 610 + 16
7. 626
