Please help me with 3 math questions!!! I will give 30 points and brainliest to whoever answers the best! 1. Write the inverse function for the function, ƒ(x) = 1/2x + 4. Then, find the value of ƒ -1(4). Type your answers in the box.ƒ -1(x) = (answer) x (answer)(answer) ƒ -1(4) = (answer) 2. Match each function with the expression representing its inverse function. Match one of the numbers with the correct letter. 1. y = x - 42. g(x) = -0.5x3. k(x) = x 4. p(x) = x + 45. h(x) = 4x 6. ƒ(x) = x/2 a. 2xb. x + 4 c. x - 4 d. -2x e. 0.25x f. x 3. The graph of a function g is shown below.Find its inverse.(picture below, my answer is NOT correct)

A bottling plant produces 1 liter bottles of soda. The actual distribution of volumes of soda dispensed to bottles is Normal, with mean μ and standard deviation σ = 0.05 liter. We randomly select 6 bottles andmeasure the volume of soda in each. The results of these 6 measurements (all in liter units) are 1.05 1.04 1.01 1.06 0.94 0.99. Based on these data, a 90% confidence interval for μ is

The function f(x)=5(x−1) is shown on the coordinate plane. Select from the drop-down menus to correctly describe the end behavior of f(x) . As x decreases without bound, the graph of f(x) . As x increases without bound, the graph of f(x) . An exponential curve graphed on a coordinate plane with horizontal x-axis ranging from negative 4 to 4 in increments of 1. The vertical y-axis ranges from negative 5 to 5 in increments of 1. The curve begins from the second quadrant. The curve increases through begin ordered pair 0 comma 0.2 end ordered pair. The curve passes through begin ordered pair 1 comma 1 end ordered pair and moves away from the positive y-axis.
