f(x) = 2x+1 Domain: All real numbers x-intercept: f(x) = 2x-1 0 = 2x-1 1 = 2+ √T = √2x ±1 = 1.4* (1,0) and (-1,0)
Answer (1)
Answer:The given function f(x) = 2x+1 has the following characteristics:* Domain: The domain of the function is all real numbers, as there are no restrictions on the values of x that can be used in the function. This is commonly expressed as (-∞, ∞).* Zero or root: The function has one real number zero or root, which occurs when f(x) = 0, i.e. when 2x + 1 = 0. Thus, the zero or root occurs when x = -1/2.* X intercept: The x intercept of the functionStep-by-step explanation:Ang function na 2x + 1 = 0 ay maaaring ma-solve para sa x gamit ang mga basic algebra skills.Una, mag-expand tayo ng expression sa kaliwa.2x + 1 = 0Sa katunayan, pagkatapos ang pag-expand. Ang function ay naging:2(x) + 1 = 0Sa susunod, i-subtract ang 1 sa pareho ng dulo ng equation.2(x) = -1Ang pagkuha sa bawat dulo sa function at pagsama-samahin ang parehong equation
