WebSep 28, 2024 · parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al foco. la fórmula de la directriz es x + p = 0 resolviendo: y^2-9x = 0 y^2 = 9x 4p = 9, entonces p = 9/4 entonces el foco tendrá la coordenada f (9/4,0) la directriz vendrá expresada por x + p = 0 x = -p x = -9/4 el problema indica que la ordenada es igual a 6, … WebTo find the answers, I can either work symbolically (like in the previous example) and then evaluate, or else I can find the values of the functions at x = 2 and then work from there. It's probably simpler in this case to evaluate first, so: f (2) = 2 (2) = 4 g (2) = (2) + 4 = 6 h (2) = 5 − (2) 3 = 5 − 8 = −3

WebThis problem presented a function fdefined by fx()=−25x2on the interval −≤ ≤55x. In part (a) students were asked to find the derivative f′()x. This involved correctly applying the chain rule to determine the symbolic derivative of f. Part (b) asked for an equation of the line tangent to the graph of fat the point where x=−3. WebUsing the definition, determine whether the function f ( x) = ( x 2 − 4) / ( x − 2) is continuous at x = 2. Justify the conclusion. Example 2.27 Determining Continuity at a Point, Condition 2 Using the definition, determine whether the function f ( x) = { − x 2 + 4 if x ≤ 3 4 x − 8 if x > 3 is continuous at x = 3.
