Use the function f(x) to answer the questions: f(x) = 2x2 − 3x − 5
2021年5月12日 · 2x - 5 = 0 and x = 2.5 x + 1 = 0 and x = -1 These are the x intercepts. B: As the coefficient of the x^2 term is positive, the parabola open up, and the vertex is a minimum. The coordinates of the parabola are given by -b/2a, f( -b/2a) where a and b represent the coefficients of a parabola in the standard form ax^2 + bx +c = 0.

2021年9月18日 · Firstly, you want to identify f(x+h). Back in algebra 2, we learned that f(x+h) means we add h to every x in our function. f(x)= -5x 2 - 2x . f(x+h) = -5(x+h) 2-2(x+h) Now our difference quotient is (f(x+h)-f(x))/(h). Previously we found f(x+h), and we know f(x), so lets plug it in. [f(x+h)-f(x)] / (h) = [-5(x+h) 2-2(x+h) - (-5x 2 - 2x)] / h ...
