The question is incomplete other wise it is really easy to solve if you now how to make the line of equation. As we know the formula to calculate the line of equation is y - y1 = m (x - x1)

Where m is the slope. y1 is the first y co ordinate. x1 is the first x co ordinate.

And the formula for slope is as we know is m = y2 - y1 divided by x2 - x1.

Where m is the slope. y2 is the second y co ordinate. y1 is the first y co ordinate. x2 is the second x co ordinate. x1 is the first x co ordinate.

How can exponential and logarithmic functions be combined

natulia [17]

Well.. .not exactly what you're asking, but the relationship of them is
${
log_{{ a}}{{ b}}=y \iff {{ a}}^y={{ b}}\qquad\qquad 
% exponential notation 2nd form
{{ a}}^y={{ b}}\iff log_{{ a}}{{ b}}=y 
}$

so... hmm to add some
for example let's say $if\ 5^3=125\textit{ that can be written also as}
\\ \quad \\
log_5(125)=3$

What is the focus of the following graph?

diamong [38]

Answer:

F(1,5)

Step-by-step explanation:

This is a vertical parabola.

The vertex is at (1,4).

The directrix is y=3.

The distance from the vertex to the directrix is p=1

The focus is (1,4+p), which is (1,4+1)

Therefore the focus is (1,5)

What are the zeros of the function? h(x)=x^3−2x^2−3x

maksim [4K]

To find the zeroes you make the function equal to zero and then solve.
$0=x^3-2x^2-3x$
Then factor out the x to get a quadratic inside the parentheses.
$0=x(x^2-2x-3)$
Factor the inside quadratic formula.
$x(x^2-2x-3)=x((x-3)(x+1))$
Lastly, use the zero product property to solve.
$x*(x-3)*(x+1)=0$
$x=0,x=3,x=-1$
