For the following exercises, find a formula for an exponential function that passes through the two points given. (0,6) and (3,7

kirill [66]

$\boxed{\boxed{f(x)=6(5)^x}}$

<h2>Explanation:</h2>

An exponential function is given by the following form:

$y=ab^x \\ \\ Where: \\ \\ a \ is \ a \ constant \ and \ b \ is \ the \ base$

Here we know two points:

$(0,6) \ and \ (3,750)$

$\bullet \ (0,6) \\ \\ x=0, \ y=6 \\ \\ 6=ab^0 \\ \\ \boxed{a=6} \\ \\\ \\ \bullet \ (3,750) \\ \\ x=3, \ y=750 \\ \\ 750=6b^3 \\ \\ b^3=\frac{750}{6} \\ \\ b=\sqrt[3]{125} \\ \\ \boxed{b=5}$

Finally, our exponential function is:

$\boxed{\boxed{f(x)=6(5)^x}}$

Which of the following equations is quadratic?

djverab [1.8K]

Answer:

The quadratic equation is (x + 3)(x + 4) = 5

Step-by-step explanation:

If the degree of a polynomial is two then the polynomial is known as a quadratic.

Now, in the given equations we see which polynomial has a degree 2.

Simplify the first equation

$x(x^2+1)=0\\x^3+x=0$

Degree is 3 and hence it is not a quadratic.

Take 2nd equation

$5(4x+2)=3\\20x+10=3$

Degree is 1 and hence it is not a quadratic.

Finally, we simplify the third equation

$(x+3)(x+4)=5$

Apply FOIL method to simplify the left hand side

$x^2+4x+3x+12=5=5$

Degree is 2 and hence it is a quadratic equation.
