If f(x)=2x+3 and g(x)=x^2+1 find f(g(3)) Help!! A.23 B.47 C.82 D.90

True [87]

Answer

A. 23

step-by-step explanation

$g(x) = {x}^{2} + 1$

We put x=3 into the function g

$\implies g(3)= {3}^{2} + 1$

$\implies \: g(3)=10$

Also,

$f(x)=2x +3$

we substitute the value of g(3) into f

$\implies f(g(3))=f(10)$

$\implies f(g(3))=f(10) = 2(10) + 3$

$\implies f(g(3))=23$

Feliz [49]

Answer:

945 ways

Step-by-step explanation:

Total

Number of Appetizers = 7
Number of main courses = 9
Number of desserts =5

Required Selection

Number of Appetizers = 2
Number of main courses = 8
Number of desserts =4

2 Appetizers out of 7 can be selected in $^7C_2$ ways

8 main courses out of 9 can be selected in $^9C_8$ ways

4 desserts out of 5 can be selected in $^5C_4$ ways

Therefore, the number of ways this can be done

$=^7C_2 \times ^9C_8 \times ^5C_4$

=945 ways
