Explanation:

a. f(2) = 2(2) = 4

b. g(-3) = (-3)²+1 = 9+1 = 10

c. h(3) = 2(3)³ = 2(27) = 54

Answer:

a) 4

b) 10

c) 54

Explanation:

Given functions:


\begin{cases}f(x)=2x\\g(x)=x^2+1\\h(x)=2(3)^x\end{cases}

Part (a)

To find f(2), substitute x = 2 into function f(x) and solve:


\begin{aligned} \implies f(2)&=2(2)\\&=4\end{aligned}

Part (b)

To find g(-3), substitute x = -3 into function g(x) and solve:


\begin{aligned} \implies g(-3)&=(-3)^2+1\\& = (-3 \cdot -3)+1 \\& = 9+1\\& = 10 \end{aligned}

Part (c)

To find h(3), substitute x = 3 into function h(x) and solve:


\begin{aligned} \implies h(3) & = 2(3)^3\\ & =2(3 \cdot 3 \cdot 3) \\& = 2(27)\\ & = 54\end{aligned}
