The education of a curve is given as y = 2x^3 -9/2 x^2 -15x + 3.
Find the value of y when x = 2
Education is good, but in math I prefer equations.
To find y when x=2, just replace all the x's with 2's and evaluate it...
y(2) = 2*2^3 -9/2 * 2^2 -15*2 + 3
beware of spell checkers ...
To find the value of y when x = 2, you need to substitute the value of x into the equation y = 2x^3 - 9/2x^2 - 15x + 3.
Here's how you can do it step by step:
Step 1: Replace x with 2 in the equation:
y = 2(2)^3 - 9/2(2)^2 - 15(2) + 3
Step 2: Simplify the exponents and perform the arithmetic operations:
y = 2(8) - 9/2(4) - 30 + 3
y = 16 - 18 - 30 + 3
Step 3: Continue to simplify the equation:
y = -2 - 30 + 3
y = -32 + 3
y = -29
So, when x = 2, the value of y is -29.
