Can someone please show steps for this? i tried using a calculator but there was no fog sign thing.

(f о g)(0) = 24

Step-by-step explanation:

f(x) = -5x - 1

g(x) = x² - 5

When you see (f о g)(#), they want you to plug the function g(x) into the function f(x).

First find g(0).

g(0) = (0)² - 5

g(0) = 0 - 5

g(0) = -5

Now plug g(0) = -5 into f(x) by replacing all x's with -5.

(f о g)(0) = -5(-5) - 1

Multiply.

(f о g)(0) = 25 - 1

Subtract.

(f о g)(0) = 24

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
