The table represents a quadratic function. Write an equation of the function in standard form.
kakasveta [241]

The equation of the quadratic function in standard form as required in the task content is; f(x) = -x² + 12x - 43.

<h3>Standard form equation of a quadratic function.</h3>

It follows from the task content that the standard form equation of the quadratic function is to.be determined.

Since the standard form equation can be derived from the vertex form equation as follows;

f(x) = a (x - h)² + k

f(x) = a (x - 6)² - 7

Hence, to find the value of a, Substitute x = 8 and f(x) = -11 so that we have;

-11 = a (8 - 6)² - 7

-11 = 4a - 7

4a = -4

a = -1.

Hence, the equation in vertex form is; f(x) = -1 (x -6)² - 7 and when expressed in standard form we have;

f(x) = -1(x² - 12x + 36) - 7

f(x) = -x² + 12x - 43

Therefore, the required equation in standard form is; f(x) = -x² + 12x - 43.

Tickets marked up 35% to 59.40 what is original price
Art [367]
So percent means parts ouf of 100
x%=x/100

so marked up form original to new price
100%=original
marku=35%
new price=100+35=135%
new price=59.40
so therefor

59.40=135/100 of original price
'of' means mutiply
replace 'origional price' with x
59.40=135/100 times x
simplify 135/100 to 27/20
59.40=27/20 times x
mutiply both sides by 20/27 to clear fraction
1188/27=x
44=x

original price=$44
