we know that

If the point belongs to the graph, then the point must satisfy the equation

we will proceed to verify each case

<u>case A.)</u> f(x)=4(x^{5})

The point is (2,80)

Verify if the point satisfy the equation

For x=2 find the value of y in the equation and compare with the y-coordinate of the point

f(2)=4(2^{5})

f(2)=128

128\neq 80

therefore

the equation f(x)=4(x^{5}) not passes through the point (2,80)

<u>case B.)</u> f(x)=5(x^{4})

The point is (2,80)

Verify if the point satisfy the equation

For x=2 find the value of y in the equation and compare with the y-coordinate of the point

f(2)=5(2^{4})

f(2)=80

80=80

therefore

the equation f(x)=5(x^{4}) passes through the point (2,80)

<u>case C.)</u> f(x)=4(5^{x})

The point is (2,80)

Verify if the point satisfy the equation

For x=2 find the value of y in the equation and compare with the y-coordinate of the point

f(2)=4(5^{2})

f(2)=100

100\neq 80

therefore

the equation f(x)=4(5^{x}) not passes through the point (2,80)

<u>case D.)</u> f(x)=5(4^{x})

The point is (2,80)

Verify if the point satisfy the equation

For x=2 find the value of y in the equation and compare with the y-coordinate of the point

f(2)=5(4^{2})

f(2)=80

80=80

therefore

the equation f(x)=5(4^{x})  passes through the point (2,80)

therefore

<u>the answer is</u>

f(x)=5(x^{4})

f(x)=5(4^{x})

What is the other solution??
Vladimir79 [104]

Answer:

The other solution is 12.

Step-by-step explanation:

Break the solution into groups: (x^2+2x)+(-12x-24)

Factor out the x^2 from the first group to get x(x+2)

Factor out the -12 out of the second group to get -12(x-12)

Here we get (x-12)(x+2)

You can see solutions are -2 and 12.
