Under these conditions, the root of this function is equal to: A )1 B) 1.5 C) 0.5 D )2 QUESTION 03 Year: 2022 Bank: IBFC – Educational Monitor The well-known Bhaskara formula is a method for finding real roots of a quadratic function. In the process of this method, the roots are found using the coefficients of the equations in the format, y = ax2 + bx + c with a, b, c ∈ R (real numbers) and even a ≠ 0. Therefore, the function given by f (x) = 4x2 - 4x + 1, has as roots the numbers: A) –1 and 3 B) 4 and – 4 C) 0 and 2 D) 1/2 and 1/2 QUESTION 04 Year: 2019 Bank: IBFC The function f(x) = -x2 + 12x, represents the total number of documents issued at time x in a public office, x is an integer between 0 and 6 hours. Under these conditions, the total number of documents issued at 3 am in this office was: A 27 B 36 C 32 D 45 QUESTION 05 Year: 2017 Bank: IBFC – Administrative Agent The sum of the coordinates of the vertex of the parabola of the function f(x) = – x2 + 8x – 12 is equal to: A 4 B 6 C 8 D 10 QUESTION 06 Year: 2017 Bank: IBFC – Middle Level Position Let the sets A = {0,1,2,3} and B = { 2,3 ,4,5,6}, you can say that the relation representing a function from A to B is: AR = {(0,2); (1.5); (2,6)} BR = {(0,3); (1.4); (2.6); (3,4)} CR = {(0,2); (1,2); (2.2); (2,3)} DR = {(0,6); (1.5);(2.4); (3,3);(0,2)} QUESTION 07 Year: 2012 Panel: IBFC – Municipal Guard The function A(t) = - t2 + 8t - 7 describes the trajectory of a ball thrown upwards until it hits the ground, where t is given in minutes and A(t) is the height (in meters) of the ball in relation to the ground. The maximum height the ball reaches is: A 10 meters B 8 meters C 6 meters D 9 meters Transcription
