Which represents a quadratic function ?
mars1129 [50]

Answer:

\boxed{\boxed{B.\ f(x)=\dfrac{3}{4}x^2+2x-5}}

Step-by-step explanation:

Quadratic function-

It is a function that can be represented by an equation of the form f = ax^2 + bx + c, where a\neq 0

In a quadratic function, the greatest power of the variable is 2.

As in the first option the highest power is 3, so it is not a quadratic function.

Even though the power of x is 2 in the third option, but as it is in the denominator, so the overall power of x becomes -2. Hence it is not a quadratic function.

As the coefficient of x^2 is 0 in case of fourth option, so it is not a quadratic function.

Equation in option 2 satisfies all the conditions of quadratic function, hence it is the quadratic function.

What is the slope y+2=1/4(x-3)
ioda

Answer:

m=\frac{1}{4}

Step-by-step explanation:

Given

y+2=\frac{1}{4}(x-3)

Required

Find the slope

y+2=\frac{1}{4}(x-3)

Subtract 2 from both sides

y+2-2=\frac{1}{4}(x-3) - 2

y=\frac{1}{4}(x-3) - 2

Open bracket

y=\frac{1}{4}x-\frac{1}{4}*3 - 2

y=\frac{1}{4}x-\frac{3}{4} - 2

Take LCM

y=\frac{1}{4}x+\frac{-3 - 8}{4}

y=\frac{1}{4}x+\frac{-11}{4}

y=\frac{1}{4}x-\frac{11}{4}

An equation has the form:

y = mx + b

Where

m = slope

By comparing: y = mx + b and y=\frac{1}{4}x-\frac{11}{4}

m=\frac{1}{4}

<em>So, the slope is 1/4</em>
