Find the equation of the exponential function represented by the table below:​

Mathematics
1 answer:
aivan3 [116]3 years ago
4 0

Answer:

I believe its y=5(4)^x

Step-by-step explanation:

The equation is supposed to look like y=ab^x

a is basically where it all starts, so where the y meets the 0

- so the 5 in the y's place meets the 0

b is what you're multiplying by on the y's side, which is by 4 every time

and the x is the exponent and since there is no exponent you leave it as x

Subtract (-9x^2+8x-14) from the sum of (-9x^2-10x) and (3x^2+3x+7)​
nalin [4]

Answer:

3x^2 - 15x + 21\\or\,\,3(x^2 -5x +7)

Step-by-step explanation:

First we will find sum of (-9x^2-10x)\,\, and\,\, (3x^2+3x+7)

Adding the like terms:

= -9x^2-10x + 3x^2 +3x+7\\= -9x^2+ 3x^2 -10x+3x+7\\= -6x^2 - 7x +7

Now subtract (-9x^2+8x-14) from (-6x^2 - 7x +7)

=(-6x^2 - 7x +7) - (-9x^2+8x-14)\\= -6x^2 - 7x +7 +9x^2-8x+14\\= -6x^2 +9x^2 - 7x -8x+7 +14\\= 3x^2 - 15x + 21\\=3(x^2 -5x +7)
