Function Operations. We learn how to find (f*g)(x) for f(x)=2x^3-5x^2 and g(x)=2x-1. We learn how to perform the indicated operation to find (f*g)(x) for f(x)=2x^3-5x^2 and g(x)=2x-1. This is a great introduction into function operations and how to perform indicated operations. This is under the topic of General Functions with this free online math video lesson. #functions #functionoperations #onlinemathlessons #minutemath #algebra2 Every Month we have a new GIVEAWAY that is FREE to Enter.

What is the radius of the circle in the figure given? We are given a circle that has two chords that are perpendicular. 3 of the chord segments have lengths of 12, 6, and 4. With just this information we can find the radius of the circle. Can you find the radius of the circle? #minutemath #mathhelp #onlinemathvideos #math #mathvideos #freemathvideos #lightboard #radiusofthecircle #circles #maths #geometry #lightboardgeometry Visit our website Math Help and Math Merch: https://minutemath.com/ Time Stamps: 00:00 - The Problem 00:54 - The Steps 06:14 - The Answer Follow us for...

Normal Lines. Find the equation of the line normal of y=-x^3+15x^2-72x+110 at (4, -2). We learn how to find the equation of the normal line of y=-x^3+15x^2-72x+110 at (4, -2). We learn how to find the equation of the line normal to the function at a given value. The normal line is the perpendicular line of the tangent line at the given point. If the normal line is a vertical line, indicate so. Our answer is in slope-intercept form. In this video, we review how to find the normal line of a function at a given point. We use common derivative properties to solve the derivative of the function which we use to find the slope of a function at a given value. We then find the perpendicular slope. We then find the y-intercept of the normal line to find the full equation of the line normal in slope-intercept form. This is a great introduction into derivatives. This is under the topic of Applications of Differentiation with this free online math video lesson. #normallines #findthenormalline #derivatives #normallineatagivenpoint #findthederivative #calculus #calculushelp #minutemath #minutemathhelp #onlinemathlessons Every Month we have a new GIVEAWAY that is FREE to Enter.
