i 7: Biết hàm số \( y=f(x) \) có đồ thị như hình vẽ dưới. Số tiệm cận của đồ thị hàm số \( y=f(x) \mid \) là \( \begin{array}{lll}\text { (A.) } 2 . & \text { B. } 3 . \\ \text { C. } 1 & \text { D. } 4\end{array} \)

An apple farm yields an average of 46 bushels of apples per tree when 26 trees are planted on an acre of ground. Each time 1 more tree is planted per acre, the yield decreases by 1 bushel (bu) per tree as a result of crowding. How many trees should be planted on an acre in order to get the highest yield?

Sketch the graph of the exponential function \( g(x) = 3^{x-1} + 2 \), indicating its asymptote.

Use transformations to graph the following function. Determine the domain, range, horizontal asymptote, and \( y \)-intercept of the function. \( f(x)=3^{x}+4 \) Which transformation is needed to graph the function \( f(x)=3^{x}+4 \) ? Choose the correct answer below. B. The graph of \( y=3^{x} \) should be shifted vertically up by 4 units. \( y=3^{x} \) should be shifted horizontally right by 4 units. D. The graph of \( y=3^{x} \) should be shifted horizontally left by 4 units. Use the graphing tool to graph the function. Dhould be shifted vertically down by 4 units. (For any answer boxes shown with the grapher, type an exact answer.) The domain of \( f(x) \) is \( \square \). (Type your answer in interval notation.)
