we are given

f(x)=2x^4-x^3+x-2

we can check each options

option-A:

-1,1

we can plug x=-1 and x=1 and check whethet f(x)=0

At x=-1:

f(-1)=2(-1)^4-(-1)^3+(-1)-2

f(-1)=0

At x=1:

f(1)=2(1)^4-(1)^3+(1)-2

f(1)=0

so, this is TRUE

option-B:

0,1

we can plug x=0 and x=1 and check whethet f(x)=0

At x=0:

f(0)=2(0)^4-(0)^3+(0)-2

f(0)=-2

At x=1:

f(1)=2(1)^4-(1)^3+(1)-2

f(1)=0

so, this is FALSE

option-C:

-2,-1

we can plug x=-2 and x=-1 and check whethet f(x)=0

At x=-2:

f(-2)=2(-2)^4-(-2)^3+(-2)-2

f(-2)=36

At x=-1:

f(-1)=2(-1)^4-(-1)^3+(-1)-2

f(-1)=0

so, this is FALSE

option-D:

-1,0

we can plug x=-1 and x=0 and check whethet f(x)=0

At x=-1:

f(-1)=2(-1)^4-(-1)^3+(-1)-2

f(-1)=0

At x=0:

f(0)=2(0)^4-(0)^3+(0)-2

f(0)=-2

so, this is FALSE

Suppose h(x)=3x-2 and j(x) = ax +b. Find a relationship between a and b such that h(j(x)) = j(h(x))
sergejj [24]

Answer:

\displaystyle a = \frac{1}{3} \text{ and } b = \frac{2}{3}

Step-by-step explanation:

We can use the definition of inverse functions. Recall that if two functions, <em>f</em> and <em>g</em> are inverses, then:

\displaystyle f(g(x)) = g(f(x)) = x

So, we can let <em>j</em> be the inverse function of <em>h</em>.

Function <em>h</em> is given by:

\displaystyle h(x) = y = 3x-2

Find its inverse. Flip variables:

x = 3y - 2

Solve for <em>y. </em>Add:

\displaystyle x + 2 = 3y

Hence:

\displaystyle h^{-1}(x) = j(x) = \frac{x+2}{3} = \frac{1}{3} x + \frac{2}{3}

Therefore, <em>a</em> = 1/3 and <em>b</em> = 2/3.

We can verify our solution:

\displaystyle \begin{aligned} h(j(x)) &= h\left( \frac{1}{3} x + \frac{2}{3}\right) \\ \\ &= 3\left(\frac{1}{3}x + \frac{2}{3}\right) -2 \\ \\ &= (x + 2) -2 \\ \\ &= x \end{aligned}

And:

\displaystyle \begin{aligned} j(h(x)) &= j\left(3x-2\right) \\ \\ &= \frac{1}{3}\left( 3x-2\right)+\frac{2}{3} \\ \\ &=\left( x- \frac{2}{3}\right) + \frac{2}{3} \\ \\ &= x  \stackrel{\checkmark}{=} x\end{aligned}

solong [7]

35 is the answer

Explanation, the sum of interrior angme is 180degree

x+(3x+40)= 180

or, 4x= 180-40

or, x= 140÷ 4

or x = 35
