Y = (4x-3)/8
8y = 4x - 3
8y+3 = 4x
(8y+3)/4 = x

f^-1(x) = (8x+3)/4

Solve for x and reverse the variables....

y=(4x-3)/8  multiply both sides by 8

8y=4x-3  add 3 to both sides

8y+3=4x  divide both sides by 4

(8y+3)/4=x so

f(x)^-1=(8x+3)/4

Work out the gradient of straight line AB where A=(-3,7) and B=(7,-8)
jolli1 [7]
I think it’s asking for you to multiply (-3,7) and (7,-8)
So if it is it would be -21 times-56= 1,176 AB=1,176

What are the zeros of the function y = x2 + 10x – 171, and why?
aleksandr82 [10.1K]
Y = x^2 + 10x - 171
y = (x - 9)(x + 19)

x - 9= 0 x + 19 = 0
x = 9 x = -19

Answer B covers all requirements... the factored form is
<span>y= (x + 19)(x - 9) </span>
<span>and the zeros are -19 and 9</span>

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients. The polynomial is x³- 7x² - 6x + 72.

<h3>What is a polynomial?</h3>

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.

The polynomial using the given information can be made as shown below.

Given the zeros of the polynomial are -3, 4, and 6.

P(x) = (x+3)(x-4)(x-6) = x³- 7x² - 6x + 72

To check the end behaviour of the function, the graph of the function can be plotted as shown in the below image.

Hence, the polynomial is x³- 7x² - 6x + 72.
