Simplify 4x+5−2x+3. Combine the like terms (4x and −2x): 4x−2x=2x. Combine constants (5 and 3; 5 + 3 = 8). Rewrite the simplified expression: 2x+8. Distributive Property. The distributive property of multiplication helps you to remove parentheses. Distributive Property Formula: a(b+c) = ab+ac. How to Use It:

How do you find the domain and range of \displaystyle{f{{\left({x}\right)}}}={2}{x}-{8} ? https://socratic.org/questions/how-do-you-find-the-domain-and-range-of-f-x-2x-8 \displaystyle{\left(-\infty,\infty\right)} for both domain and range Explanation: Since the equation is a line, all values of \displaystyle{x} produce a real value of ...

How do you find the inverse of f (x)= x2 −2x−8 and is it a function? The inverse of \displaystyle {f { {\left ( {x}\right)}}}= {x}^ { {2}}- {2} {x}- {8} is \displaystyle {\left (\text {XXX}\right)}\overline { { {f}}} {\left ( {x}\right)}= {1}\pm\sqrt { { {x}+ {9}}} which is not a ...

2017年7月5日 · f (x) = x2 − 2x − 8 is a quadratic equation in standard form: ax2 +bx + c, where a = 1, b = −2, and c = − 8. Determine the axis of symmetry, x. x = −b 2a. x = −(− 2) 2 ⋅ 1. x = 2 2 = 1. x = 1 is also the x value of the vertex. Determine the y value of the vertex by substituting y for f (x), and substituting 1 for x. y = 12 − 2(1) − 8. Simplify.

Write f (x) = 2x2 − 8 f (x) = 2 x 2 - 8 as an equation. y = 2x2 −8 y = 2 x 2 - 8. Interchange the variables. x = 2y2 −8 x = 2 y 2 - 8. Solve for y y. Tap for more steps... y = √2(x+8) 2 y = 2 (x + 8) 2. y = − √2(x+8) 2 y = - 2 (x + 8) 2. Replace y y with f −1(x) f - 1 (x) to show the final answer.

2019年1月22日 · Let y = x2 - 2x - 8. The following table gives the values of y or f (x) for various values of x. Let us plot the points (-4, 16), (-3, 7), (-2, 0), (-1, -5), (0, - 8), (1, - 9), (2, - 8), (3, - 5), (4, 0), (5, 7) and (6, 16) on a graphs paper and draw …
