WebJul 26, 2015 · Investigate the sign of the second derivative, f''(x) For f(x)=x^3+3x^2+5x+7, we have f'(x)=3x^2+6x+5 and f''(x) = 6x+6 f''(x) = 0 at x= -1, so we check the sign of f'' on each side of -1 f''(x) is negative (that is f''(x) < 0) for x < -1. So the graph of f is concave down on (-oo, -1). f''(x) >0 for x > -1, so the graph of f is concave up on (-1,oo) The point … Webf (x) = 3x − 7 f ( x) = 3 x - 7. Rewrite the function as an equation. y = 3x− 7 y = 3 x - 7. Use the slope-intercept form to find the slope and y-intercept. Tap for more steps... Slope: 3 …

WebA graphing calculator can be used to graph functions, solve equations, identify function properties, and perform tasks with variables. What role do online graphing calculators play? Graphing calculators are an important tool for math students beginning of first year algebra. It helps with concepts such as graphing functions, polynomials ... WebLinear Functions. Since we are only given one side of the equation and not the other side of the equation, solving this equation can either mean finding the value of f(x) f ( x) at different values of the variable "x" or by plotting this line on the cartesian coordinate system where we work under the assumption that y =f(x) = 3x+7 y = f ( x ... how to say good under pressure

WebIn this video we'll draw the graph for y = 3x + 7. You may also see this written as f(x) = 3x + 7. First, we will use a table of values to plot points on the... WebOn the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f(x) = 5x + 1, then the slope is just 5 everywhere, so f'(x) = 5. Then f''(x) is the slope of a horizontal line--which is 0. So f''(x) = 0. See if you can guess what the third derivative is, or the ... Webx2 − 3x − 7 x 2 - 3 x - 7. Find the properties of the given parabola. Tap for more steps... Direction: Opens Up.
