Which values of a and b in the exponential function y = a times b Superscript x would result in the following graph? On a coordi

galina1969 [7]

Answer:

$a =-3$ $b =2$

Step-by-step explanation:

Given

$y = ab^x$

$(x_1,y_1) = (0,-3)$

Required

Find a and b

Substitute $(x_1,y_1) = (0,-3)$ for x and y in $y = ab^x$

$-3 = ab^0$

$-3 = a * 1$

$-3 = a$

Rewrite as:

$a =-3$

The above implies that (a) is correct;

Hence:

$a =-3$ $b =2$

So, the equation is:

$y = -3(2)^x$

Use FOIL and the distributive property to derive (a-b)^3

Sergio039 [100]

Answer:

(a-b)^3 = $\left(a-b\right)^3=a^3-3a^2b+3ab^2-b^3$

Step-by-step explanation:

(a-b)^3 = (a-b)(a-b)(a-b)

According to the perfect cube formula (a-b)^3 = $\left(a-b\right)^3=a^3-3a^2b+3ab^2-b^3$

And there you have it! The perfect cube formula already solved your equation!

Please help me!!! I don't understand this at all

Varvara68 [4.7K]

a) First, multiply the numbers 8 and 2, and we get 16.

Now, we have to multiply 16 and the algebraic notation “y”, we get the result of 16y.

<h3><u>Whenever you multiply the number(s) with algebraic notations, you need to multiply the number(s) and write the algebraic notation at the end.</u></h3>

<u></u>

b) Multiply the number 8 and the algebraic notation “y”, and we get the result 8y.

<em>Hope this helps :)</em>
