Form quadratic functions given the following information:<br> Zeroes at 4 and –2, f(0)=4

laila [671]

Answer:

$f(x)=-0.5x^2+x+4$

Step-by-step explanation:

we know that

A quadratic function in factored form is equal to

$f(x)=a(x-x_1)(x-x_2)$

where

a is the leading coefficient

x_1 and x_2 are the zeroes of the function

substitute the given values

$f(x)=a(x-4)(x+2)$

Find the value of a

Remember that

For x=0 ----> f(0)=4

substitute

$4=a(0-4)(0+2)$

$4=a(-8)\\a=-0.5$

so

$f(x)=-0.5(x-4)(x+2)$

$f(x)=-0.5(x^2+2x-4x-8)$

$f(x)=-0.5(x^2-2x-8)$

$f(x)=-0.5x^2+x+4$

What are the domain and range of the function f(x)=-3(x-5)squared+4

svet-max [94.6K]

Domain is all real numbers
range
hmm
we know that x^2=a positive number
then multiply it by that negative -3
therefor the range is going to be mostly negative
if we make the x-5 equal to zero, then there is no negative, so
wher x=5, then f(5)=0+4=4
the highest positive number you can get is f(5)=4

so therfor

domain=all real number
range is x≤4

Given g(x)=Squareroot x-4 and h(x)=2x-8, what is g(h(10))

yan [13]

Answer:

$g(h(10)) = 2\sqrt 2$

Step-by-step explanation:

Given

$g(x) = \sqrt {x - 4$

$h(x) = 2x - 8$

Required

$g(h(10))$

First, calculate $g(h(x))$

We have:

$g(x) = \sqrt {x - 4$

This gives:

$g(h(x)) = \sqrt {h(x) - 4$

Substitute $h(x) = 2x - 8$

$g(h(x)) = \sqrt {2x - 8 - 4$

$g(h(x)) = \sqrt {2x - 12$

Substitute $x = 10$

$g(h(10)) = \sqrt {2*10 - 12$

$g(h(10)) = \sqrt {20 - 12$

$g(h(10)) = \sqrt {8\\$

Split

$g(h(10)) = \sqrt {4} * \sqrt 2$

This gives

$g(h(10)) = 2\sqrt 2$
