Simplify when x=4 3x^3+3

The value is 195 When x = 4 in 3x³ + 3.

Step-by-step explanation:

3x³ + 3

Insert 4 for x.

3(4)³ + 3

Cube the 4.

3(64) + 3

Multiply 3 by 64.

192 + 3

Add.

195

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
