Answer:

the y intercept is (0,1) and the slope is 3

that means the y = mx + b format would be:

y = 3x + 1

Answer:

y=3x+1 or Slope:3 and Y intercept: (0,1)

Step-by-step explanation:

Use the slope formula and the slope-intercept form to find the slope m and y-intercept b .

Formula : y=mx+b

Multiply (3x2-4x+5)(x2-3x+2)

Iteru [2.4K]

So with this, you can rewrite the equation as: $(3x^2\times x^2)+(3x^2\times -3x)+(3x^2\times 2)+(-4x\times x^2)+(-4x\times -3x)+(-4x\times 2)+(5\times x^2)+(5\times -3x)+(5\times 2)$

Firstly, solve the multiplication: $3x^4+(-9x^3)+6x^2+(-4x^3)+12x^2+(-8x)+5x^2+(-15x)+10$

Next, combine like terms, and <u>your answer will be: $3x^4-13x^3+23x^2-23x+10$ </u>

Find the derivative of f(x) = 2x^2 - 4x +3

ivolga24 [154]

Explanation

$2x^2-4x+3$

When taking derivatives of polynomials, we primarily make use of the power rule.

Power rule.

$\begin{gathered} f(x)=x^n \\ \text{then} \\ f^{\prime}(x)=nx^{n-1} \end{gathered}$

also, the derivate of a sum is the sum of the derivates

hence

$\begin{gathered} g(x)=f(x)+h(x)+\ldots z(x) \\ g^{\prime}(x)=f^{\prime}(x)+h^{\prime}(x)+\ldots.z^{\prime}(x) \end{gathered}$

Step 1

apply:

$\begin{gathered} f(x)=2x^2-4x+3 \\ f^{\prime}(x)=2\cdot2x^{2-1}-4(1)x^{1-1}+ \\ f^{\prime}(x)=4x^{}-4(1)x^0+3^0 \\ f^{\prime}(x)=4x^{}-4(1)(1) \\ f^{\prime}(x)=4z-4 \end{gathered}$

therefore, the answer is
