to which family does the function y=(x 2)1/2 3 belong? a: quadratic b: square root c: exponential d :reciprocal
Neko [114]

Answer:

option a is correct.

Step-by-step explanation:

We have given the equation:

y=x+\frac{1}{2}^{\frac{1}{2}}+3

Squaring both sides of the above equation we get:

y^2=(x+\frac{1}{2})^2+9+2\cdot(x+\frac{1}{2})(3)

After simplifying the first  step

y^2=x^2+\frac{1}{4}+x+9+3(2x+1)

y^2=x^2+x+6x+3+9+\frac{1}{4}

y^2=x^2+7x+12+\frac{1}{4}

After final simplification we get:

4y^2=4x^2+28x+49

We are getting quadratic equation since, the degree in resultant is 2.

Therefore, option a is correct.

Find the vertex of the parabola y = 8x2.
murzikaleks [220]

Answer:

vertex is at (0,0)

Step-by-step explanation:

Find the vertex of the parabola y = 8x2.

I assume you meant   y =  8* x^2

this can be compared to the general vertex form  y = a (x - h)^2 + k

where vertex at  (h, k)

so then...

h =0  and k = 0 here

vertex is at (0,0)

What is the difference of the fractions? Use the number line to help find the answer
alisha [4.7K]

Answer:

-7/10

Explanation:

Given the expression

\frac{1}{2}-1\frac{1}{5}

We can rewrite the expression as:

\frac{1}{2}-\frac{6}{5}=\frac{5}{10}-\frac{12}{10}

The number line showing the location of the two numbers is attached below. Therefore:

\frac{5}{10}-\frac{12}{10}=-\frac{7}{10}
