Answer:

f(4)=47

Step-by-step explanation:

To find the answer, replace the x’s in the equation with 4. This would make the equation 3(4)^2 + 4 - 5. According to PEMDAS, you would first raise 4 to the power of 2 (16) then multiply it by 3 (48). This makes the equation 48 + 4 - 5. You just need to add and subtract from here. 48+4=52. 52-5=47

What is the product of -2x^3+x-5 and x^3-3x-4 ?
murzikaleks [220]
To find the product of <span>-2x^3+x-5 and x^3-3x-4, we need to multiply each term in the first polynomial by the second polynomial. (So, x^3 - 3x - 4) times ....
-2x^3 = -2x^6 + 6x^4 + 8x^3
x = x^4 - 3x^2 - 4x
-5 = -5x^3 + 15x + 20
If we add all these together, we get (-2x^6 + 7x^4 + 3x^3 - 3x^2 + 11x + 20)</span>
