Question
What is the y-intercept of the polynomial f, of, xf(x) defined below? Write the y-value only.f, of, x, equals, minus, 10, x, cubed, minus, 4, x, plus, 3, x, squared, minus, x, to the power 6 , minus, 5f(x)=−10x 3 −4x+3x 2 −x 6 −5
Solution
The y-intercept of a polynomial is the value of the function when x equals 0. In this case, when we substitute x=0 into the function f(x) = -10x^3 - 4x + 3x^2 - x^6 - 5, all terms that contain x will become 0. Therefore, the y-intercept of the function is -5.
