Question
Scientific notation. Simplify of radicals and rationalize the denominators. Write complex numbers delta + tau d. Applied problems must have the verities identified and an equation for full credit. MULTIPLE CHOICE ack the box of the one alternative best completes the statement or answer the question. Determine whether the first function to the right is even, odd, or neither even or odd. Neither Odd Even Determine the intervals on which the functions to the right is increasing, decreasing and constant. Ignore the endpoints. Increasing on (-infinity, -1); Decreasing on (-1, infinity) Increasing on (1, infinity); Decreasing on (-infinity, 1) Increasing on (-infinity, 1); Decreasing on (1, infinity) Increasing on (-1, infinity); Decreasing on (-infinity, -1) Given the function f_x, match the function g with a transformation of f. f(x) = x^2 - 3 and g(x) = x^1 - 4 f(x) + 1 f[x + 1] f(x) - 1 f[x - 1] None of these A rectangular sign is being designed so that the length of its base, in feet, is 20 feet less than the height, h. Express the area of the sigh as a function of h. A[h] = -20h^2 + 2h A[h] = -20h + h^2 A[h] = -20h + 4h^2 A[h] = 20h - 2h^2 None of these How can the graph of f(x) = 4/y + 11 be obtained from the graph of y = 1/x? Shift it horizontally 4 units to the right. Shift it 11 units up. Stretch it vertically by a factor of 4. Shift it 11 units to the right. Shift it horizontally 4 units to the left. Shift it 11 units down. Shrink it vertically a factor of 1/4. Shift it 11 units up. None of these
Explanation / Answer
1) Geometrically speaking, the graph face of an even function is symmetric with respect to the y-axis.
Geometrically, the graph of an odd function has rotational symmetry with respect to the origin,
So, given graph is odd.
2) function is decreasing in interval (- inf , -1)
function is decreasing in interval ( -1 , inf)
