Can you pls. me how to solve this?

y = - x -

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y-intercept )

y = 2x - 3 is in this form with slope m = 2

given a line with slope m , then the slope of a line perpendicular to it is

= - = -

y = - x + b ← is the partial equation

too find b substitute (1, - 3) into the partial equation

- 3 = - + b ⇒ b = - 3 + = -

y = - x - ← equation of line

Step-by-step explanation:

perpendicular to y = 2x - 3  

Input the slope and the point (x₁, y₁) = (1, -3) into the Point-Slope formula:    y - y₁ = m(x - x₁)

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
