Iwill give brainliest, 30 points the graph below shows three functions: graph of function f of x equals 2 to the power of negative x. graph of function g of x equals 5 to the power of x. graph of p of x is a line segment connecting points negative 1, negative 3 and 2, 12. which function has all real numbers as its domain? only f(x) both g(x) and p(x) both f(x) and g(x) only p(x)

Only p(x) has all real numbers as its domain

Step-by-step explanation:

The given functions is:

g(x) = 5ˣ

p(x) = (1, 3) and (2, 12)

To find equation of the line passing through points (x₁,y₁) and (x₂,y₂), (x₁≠x₂). We use formula:

where,(x₁,y₁) = (1, 3) and (x₂,y₂) = (2,12)

Hence, p(x) = y = 9x − 6

Here, both f(x) and g(x) is exponential function and p(x) is linear function.

Also here f(x) is not defined in large negative value, hence its domain is not all real numbers.

And g(x) is not defined in large positive value, hence its domain is not all real numbers.

But p(x) is defined over all real numbers, hence Only p(x) has domain of all real numbers.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
