This function is consist of two subfunction with different domains.

f(-1) means x= -1 ≤ 1 and we will use subfunction -x+2 => f(-1)=-(-1)+2= 1=2=3

f(3) means x=3 > 1 and we will use subfunction x∧2-4x+6 =>

f(3)= 3∧2-4*3+6= 9-12+6=3

Good luck!!!

Find the value of 4x if x/2=3

Doss [256]

Answer:

24

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

x/2 = 3

x = 3×2

x = 6

Therefore

4x = 4 × 6

4x = 24

1.Which expressions are polynomials? Select each correct answer. Pick more then one.

madreJ [45]

If all the power of the variables are greater than or equal to zero, then the expression is a valid polynomial.

So,

1.

$7x^{7}-x-5$

$35x^{2}$

$\frac{x}{5}+2$

are polynomials.

2.

$x^{2} -x\sqrt{2}$

y

2 + s

$4x^{2} +y$

are all polynomials.

3.

If the degree of the polynomial is 3, then it is a cubic polynomial. If the number of terms of a polynomial is 3, then it is a trinomial.

Hence, $-5x^{3}-4x+1$ is a cubic trinomial.

4.

The highest power is the degree.

Hence, degree of the polynomial is 2 + 4 = 6.

Could someone explain this to me

Bond [772]

Answer:

Step-by-step explanation:

The question is asking you to graph the equations.

The equations are in slope intercept form so y=mx+b

M is the slope and b is the y-intercept

First draw the y & x axis and label/number them

The y-intercept for the first equation is -1 so draw a dot on the -1 on the y-axis

The slope is 2/5 and you use rise/run to continue the slope.

you rise 2 on the y-axis and go right 5 times on the x-axis (for a negative number you go left/down)

For the second equation, you have to turn it into slope intercept form.

You should get y=2/3x+3

You graph this equation the same as you did the first one.
