Which equation represents an exponential function that passes through the point 2,36

Hi! here you want a function that pases through the point (2,36)

it means, a function f(x) so f(2) = 36.

Also, f(x) must be an exponential function, this means that f(x) =

where a is a real number.

then   = 36

so a = = ± 6.

then your function can be f(x) = or .

Notice that i used a very simplest example of exponential function. You actually can found lots of exponential functions F(x) that passes through the point (2,36).

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.
