What is the value of the expression when x = 4? 3x2 1.36 2.48 3.12 4.24

The correct answer is Option 2. 48

Step-by-step explanation:

The given equation is  3x²  ---(1)

When we substitute the value of x we get the value of the equation.

Here it is given that,

x = 4

Substitute this value in the equation (1) we get,

3x²  = 3*(4)² = 3*16 = 48

Therefore the correct answer is Option 2. 48

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

i believe that the slope of the line is -5
