Webf (x)= √ (x+4) -2 and you are trying to find f (x+2) The "x+2" is your input value. You replace the "x" in the function with "x+2" The "x" is inside the square root. So, that "x" changes to "x+2" f (x+2)= √ (x+2+4) -2 What you calculated is f (x)+2. The 2 in your scenario is not an input. You just added 2 to the entire function. WebMar 26, 2016 · You can move a sine curve up or down by simply adding or subtracting a number from the equation of the curve. For example, the graph of y = sin x + 4 moves the …

WebApr 19, 2024 · Shifting the parent graph of y = sin x to the right by pi/4. Move the graph vertically. The sinusoidal axis of the graph moves up three positions in this function, so … WebThe graph of y=f(x)+k (where k is a real number) is the same as the graph of y=f(x) only it's shifted up (when k>0) or down (when k 0). Similarly, the graph of y=f(x-h) (where h is a real number) is the same as the graph of y=f(x) only it's shifted to the right (when h>0) or to … When x is four, instead of getting positive two, you're now going to get negative tw… ramzi jouida

WebThe vertical shift results from a constant added to the output. Move the graph up for a positive constant and down for a negative constant. The horizontal shift results from a constant added to the input. Move the graph left for a positive constant and right for a negative constant. Apply the shifts to the graph in either order. WebTo use a calculator to solve this, press [Y=] and enter 1.2(5)x+2.8 1.2 ( 5) x + 2.8 next to Y1=. Then enter 42 next to Y2=. For a window, use the values –3 to 3 for x x and –5 to 55 for y y .Press [GRAPH]. The graphs should intersect somewhere near x= 2 x = 2. For a better approximation, press [2ND] then [CALC]. WebIdentify the vertex and axis of symmetry for a given quadratic function in vertex form. The standard form of a quadratic function presents the function in the form. f (x)= a(x−h)2 +k f ( x) = a ( x − h) 2 + k. where (h, k) ( h, k) is … dr juan david osorio
