a.) f(1)
I need the full solution for this please help me out.

Answer 1

Answer:

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

f(1)=1-5-7+4

f(1)=-7

Answer 2

Given data: $f(1)=x^3-5x^2-7x+4$.

To find: $f(1)$.

Solution:

• Function is defined the relationship between the one variable and another.
• $f(x)=x$ is the function and it contains all the real numbers.
• Function has domain and range. Domain contains unique values and it can be mapped with range (one -many relation).
• $x^3-5x^2-7x+4$ in the given equation x value is 1.
• Substituting $x = 1$ we get, $1^3-5(1)^2-7(1)+4$.
• Simplifying the equation it gives $1-5-7+4$.
• Hence the function of given equation is $f(1)=-7$.
