Step-by-step explanation:

f(x) = 3x⁴ - 5x² + 2x - 3

When x = -1,

f(-1) = 3(-1)⁴ - 5(-1)² + 2(-1) - 3 = 3 - 5 - 2 - 3 = -7.

Over [174]

Answer:

f(x)=(x-1)^2-7

Step-by-step explanation:

Standard form:

f(x)=x^2-2x-6

Vertex form:

y=(x-h)^2+k

(h, k) is the vertex

x is the coordinate of the vertex

To find x use the formula:

x=\frac{-h}{2a}

f(x)=x^2-2x-6

a=1

b=-2

c=-6

Substitute:

x=\frac{-(-2)}{2(1)}=1

Substitute x in equation:

f(x)=1^2-2(1)-6\\f(x)=1-2-6\\f(x)=-7

h=1

k=-7

Substitute h, and k into the vertex formula:

f(x)=(x-1)^2-7
