Contoh soal 5. Selesaikanlah persamaan dengan tanda kurung berikut. 3(x + 6) = x + 2; 6x - (2x - 9) = 11; 9x - 2(3x + 5) = 2; 7(x - 2) = 4 f ( x) = 2 x 2 - 3. Solution: Well, you can use an online odd or even function calculator to check whether a function is even, odd or neither. For this purpose, it substitutes - x in the given function f ( x) = 2 x 2 - 3 and then simplifies. f ( x) = 2 x 2 - 3. Now, plug in - x in the function, f ( − x) = 2 ( − x) 2 - 3. Simplify (2x-3) (x+7) (2x − 3) (x + 7) ( 2 x - 3) ( x + 7) Expand (2x−3)(x+ 7) ( 2 x - 3) ( x + 7) using the FOIL Method. Tap for more steps 2x⋅x+2x⋅7−3x−3⋅7 2 x ⋅ x + 2 x ⋅ 7 - 3 x - 3 ⋅ 7.

Try it now: 2x+3=15 @ x=6 Clickable Demo Try entering 2x+3=15 @ x=6 into the text box. After you enter the expression, Algebra Calculator will plug x=6 in for the equation 2x+3=15: 2(6)+3 = 15. The calculator prints "True" to let you know that the answer is right. More Examples Identify the piece that describes the function at x = 5 x = 5. In this case, x = 5 x = 5 falls within the interval 3 < x < 7 3 < x < 7, therefore use 3x 3 x to evaluate f (5) f ( 5). f (x) = ⎧ ⎨⎩3−5x x ≤ 3 3x 3 < x < 7 5x+1 x ≥ 7 f ( x) = { 3 - 5 x x ≤ 3 3 x 3 < x < 7 5 x + 1 x ≥ 7. The function is equal to 3x 3 x at x = 5 x = 5 Solve Using the Quadratic Formula 3x^2+x-5=0. 3x2 + x − 5 = 0 3 x 2 + x - 5 = 0. Use the quadratic formula to find the solutions. −b±√b2 −4(ac) 2a - b ± b 2 - 4 ( a c) 2 a. Substitute the values a = 3 a = 3, b = 1 b = 1, and c = −5 c = - 5 into the quadratic formula and solve for x x. −1±√12 −4⋅ (3⋅−5) 2⋅3 - 1 ± 1 2 Two numbers r and s sum up to -\frac{5}{2} exactly when the average of the two numbers is \frac{1}{2}*-\frac{5}{2} = -\frac{5}{4}. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C. Factor f(x)=x^3+2x^2-5x-6. Step 1.

Ask Question Answer: x = -7/5. Step-by-step explanation: (3)(x)+(3)(−6)+−8x = −2+(5)(2x)+(5)(1) 3x+−8x+−18 = 10x+−2+5 −5x+−18 Yes: Assuming f (x)= 0 if x= −1, or x =2, then one possible function for f (x) will be f (x)= (x+1)(x−2). And we are given g(x) =2x−1. If this is the case, it follows that (f ∘ g)(x) =f (g(x))= (2x)(2x−3) How do you find (g ∘ f)(−2 + x) given g(x) = 2x − 2 and f (x) = x2 + 3x 2x2 −2x−6 Explanation: The first step is .
