Question

what is the value of f(x)=5x-4x2+3 when x= -1​

Answer 1

Answer:

Here is the answer =>

$\huge\bf\purple{Answer}$

Step-by-step explanation:

Equation=>5x-4x^2+3

Zero=>x=-1

So p(x)5x-4x^2+3

p(-1) => 5(-1)-4(-1)^2+3

=> -5-4+3

=>-9+3

=>-6.

So the value of the equation 5x-4x^2+3 when x=-1 is -6 which is the required answer.

Answer 2

Concept:

A function can be defined as a relation between a set of inputs having one output each, input is known as the independent variable, and output is known as the dependent variable.

The value of the given function at any point can be calculated by substituting the value of the point in the given function.

Given:

The given function is f(x)=5x-4x²+3.

Find:

The value of the function when x= -1​.

Solution:

Substituting the value of the x= -1​, in the given function is f(x)=5x-4x²+3,

f(x) = 5x-4x²+3

f(-1) = 5(-1)-4(-1)²+3

f(-1) = -5-4(1)+3

f(-1) = -5-4+3

f(-1) = -9+3 = -6

Hence, the value of the function f(x)=5x-4x²+3 at x= -1​ is -6.
