WebFeb 23, 2024 · See below. Exponential functions with no vertical transformation never cross the x axis. As such, y = 8^x will have no x-intercepts. It will have a y-intercept at y(0) = 8^0 = 1. The graph should resemble the following. graph{8^x [-10, 10, -5, 5]} The graph of y = 8^(x + 1) is the graph of y = 8^x moved 1 unit to the left, so that it's y-intercept now lies … Web3.By graphing method. Example 2. Solve: #f(x) = x^2 + 2x - 3 < 0#. The graph of f(x) is an upward parabola (a > 0), that intersects the x-axis at x1 = 1 and x2 = - 3. Inside the interval (-3, 1), the parabola stays below the x-axis --> f(x) < 0. Therefor, the solution set is the open interval (-3, 1) graph{x^2 + 2x - 3 [-10, 10, -5, 5]}

WebMay 27, 2024 · one way is to find the intercepts and draw a. straight line through them. to find the intercepts. ∙ let x = 0, in the equation for y-intercept. ∙ let y = 0, in the equation for x-intercept. x = 0 → 0 − 5y = 80 ⇒ y = − 16 ← y-intercept. y = 0 → 8x −0 = 80 ⇒ x = 10 ← x-intercept. plot these 2 points and draw a straight line ... WebThen, notice that under the second radical sign, you've got a shift to the left by 3/2. To show how this process makes sense, try graphing both y = sqrt(2x+3) and y = sqrt(2) * sqrt(x+3/2). You should get the same thing. To graph it, know what the graph of y = sqrt(x) looks like first (its a parabola on its side with only the top half). eagle claw fishing rods combo

Web4.2 Solving -9x 2-8x-8 = 0 by Completing The Square . Multiply both sides of the equation by (-1) to obtain positive coefficient for the first term: 9x 2 +8x+8 = 0 Divide both sides of the equation by 9 to have 1 as the coefficient of the first term : x 2 +(8/9)x+(8/9) = 0 Subtract 8/9 from both side of the equation : x 2 +(8/9)x = -8/9 WebSee the entire solution process below: Explanation: First, sole the second equation for y : −2x = y+ 4 −2x −(4) = y+ 4−(4) ... How do you find the slope and intercept of 3x + 4y = 16 ? slope is : −43 intercept is : 4 Explanation: First convert the given equation in the slope intercept form of a straight line.
