A quadratic function is shown. f(x) = -x^2+7x-12 one factor of this function is (x-4). What is the other factor of the quadratic

Alexus [3.1K]

Answer:

The other term is (x-3)

Step-by-step explanation:

The quadratic function is:

$f(x)=-x^{2}+7x-12$

Factoring this function we will have:

$f(x)=-(x-4)(x-3)$

Therefore, the other term is (x-3).

I hope it helps you!

Calculate the axis of symmetry in the equation Y = (x+1) (x-4)

algol [13]

Answer:

Every parabola has a turning point called the axis of symmetry,so for this question you just have to find the turning points

x turning point= -b/2a,and the y turning point is gotten by replacing the value of x in the equation

y=(x+1)(x-4)

=x^2-3x-4

a is 1,b is -3 and c is -4

x= -(-3)/2(1)

=1.5

and y=x^2-3x-4

=1.5^2-3(1.5)-4

= -6.25

therefore the axis of symmetry is (1.5,-6.25)

I hope this helps
