Find the y-intercept of f(x)=3x^2 -2x-8

-8

Step-by-step explanation:

y-intercept of f(x)=3x^2 -2x-8  when : x =0

f(0) = 3(0)² -2(0) -8 = - 8

The y-intercept of y = f(x) =  is -8.

Solution:

From question, given equation is f(x) =

We have to find the y-intercept of the above equation

The y-intercept of the graph is the point where the function crosses the y-axis.  The x-value is equal to zero for every point on the y-axis.

From question given that

--- eqn 1

On substituting x = 0 in equation (1), the above equation becomes

On simplifying, we get

y = 0-0-8

y = -8

So the y-intercept of f(x) =

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
