Use Goal Seek to find where the given equation has the desired value. Let f(x) = -x2 + 4x + 5. Find an x so that f(x) = -5.
Added by Ian M.
Step 1
We have \( f(x) = -x^2 + 4x + 5 \) and we want to find \( x \) such that \( f(x) = -5 \). This gives us the equation: \[ -x^2 + 4x + 5 = -5 \] Show more…

Use the "guess" method to solve for x in the following equations. a) x² + 6x⁷ - (6 - x^5/9) / (x² - 1) = 47.6 b) (x² + x⁵) / x³ - 1 = x Use goal seeker function to solve the following equation. c) (6x^0.45 / √ x) - xe^(x/2) + x² = 10 d) Find Φ in degrees. 0.5113 = (cos Φ)² / (π sin Φ)

Use each graph to estimate the values of $x$ for which $f(x)=5 .$ Then write and solve an equation to find the values of $x$ such that $f(x)=5 .$ Round to the nearest hundredth. $$ f(x)=-\frac{1}{2} x^{2}+2 x+6 $$

c) Use your spreadsheet to estimate the value of x in the interval [0,1] for which f(x) assumes its minimum value. Give your answer correct to 2 decimal places. Consider the function f(x) = 3 + 2""(4 + 2x). Suppose we wish to know the value of x where this function assumes its minimum value on the interval [0,1]. Later in the course, we will learn how to compute this value analytically, but for now, let's compute it numerically using a spreadsheet. Open a spreadsheet program such as Excel or Google Sheets (available for free online) and create a spreadsheet that looks like the one below. Assume all cells not shown begin blank. A downwards arrow indicates the contents from the cell above will be copied down.
