What is f(-2) for the function f(x)= -3x + 8

Step-by-step explanation:

Given function:

To find

For the given linear function the value represents the input values of the function or the domain of the function while represents the output values or the range of the function and is often refereed to as the values of the function.

In order to find we will plugin -2 in place of in the function and evaluate it. It means our input value =-2 and we need to calculate the output value.

Thus,

   [ Product of two negative numbers is a positive number]

∴ (Answer)

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
