Input 0 for x, because the y-intercept is on the y-axis.

G(0) = 3(0) - 2

Simplify.

G(0) = -2

The answer is A, (0, -2)

Given the function: f(x) = 2x3 - 3/2x, find f(-4).

Sergeu [11.5K]

Answer:

D) -122

Step-by-step explanation:

Given:

$f(x) = 2x^3-\frac{3}2x$

We need to find f(-4).

Now by substituting the value of x =-4 in above equation we get;

$f(-4)= 2\times(-4)^3-\frac{3}{2}\times(-4)\\$

By using PEDMAS we will solve for exponential function first we get;

Now we know that $(-4)^3=-64$

So we get;

$f(-4)= 2\times(-64)-\frac{3}{2}\times(-4)\\$

Now using PEDMAS we will solve division.

$f(-4)= 2\times(-64)-1.5\times(-4)$

Now using PEDMAS we solve multiplication.

$f(-4)= -128+6$

Finally by subtraction we get;

$f(-4)= -122$

if f(x)=3/x+2-sqrtx-3 complete the following statement. The domain for f(x) is all real numbers___ than or equal to 3

Stolb23 [73]

The domain of the function is the set of all the values of x that would allow the function to have real values. Since the radicand is x - 3, the value of x cannot be less than 3 because that would make the value of sqrt (x - 3) an imaginary number. Thus, the domain should be all numbers GREATER than or equal to 3.
