determine the maximum or minimum of the quadratic function. express your answer in the form (x,y) and using decimals rounded to
kolezko [41]

We are given the following quadratic equation

f(x)=2x^2+7x-10

The vertex is the maximum/minimum point of the quadratic equation.

The x-coordinate of the vertex is given by

h=-\frac{b}{2a}

Comparing the given equation with the general form of the quadratic equation, the coefficients are

a = 2

b = 7

c = -10

h=-\frac{b}{2a}=-\frac{7}{2(2)}=-\frac{7}{4}=-1.75

The y-coordinate of the vertex is given by

\begin{gathered} f(x)=2x^2+7x-10 \\ f(-1.75)=2(-1.75)^2+7(-1.75)-10 \\ f(-1.75)=2(3.0625)^{}-12.25-10 \\ f(-1.75)=6.125^{}-12.25-10 \\ f\mleft(-1.75\mright)=-16.13 \end{gathered}

This means that we have a minimum point.

Therefore, the minimum point of the given quadratic equation is

(-1.75,-16.13)

A gym membership charges $100 for a start up fee and $40 a month for
slamgirl [31]

The equation that represents the cost of membership is  $100 + $40c

The cost of 1 year membership is $580.

The number of months you have paid for is 9 months.

<h3>What is the equation that represents the cost of the gym membership?</h3>

The cost of gym membership is the sum of the fixed cost and the variable cost. The fixed cost is the start-up fee while the variable cost is the cost per month.

The equation that represents the cost of the gym membership is: c = $100 + $40m

Where m represents the number of months

The cost of 1 year membership =  $100 + $40(12)

$100 + $480 = $580

How many months would $460 cover = ($460 - $100) / 40 = 9 months
