<h3>What is function?</h3>
An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)
Given:
f(x)= 2x+3 and g(x)= x²-5.
a) (f+ g)(3)
= f(3)+ g(3)
= 2(3)+3 + (3)²-5
=6+3+9-5
=13
b) (f-g)(4)
= f(4)- g(4)
= 2(4)+3 - (4)²+5
=8+3-16+5
= 0
c) (fg)(-2)
= f(-2)*g(-2)
=[ 2(-2)+3][(-2)² -5 ]
=(-1)(-1)
= 1
d) (g/f)(3)
= g(3)/f(3)
= 3²-5/ 2(3)+3
= 4/9

Answer:
The rule for a line whose gradient is -4 and y-intercept = 8 is
Step-by-step explanation:
Equation of line slope intercept form is
------------- (1)
Where m is slope or gradient and b is y-intercept
<u>Here</u>
Substituting values in equation (1)
It has been given that ER + LM = NP
and LM = 7
Substituting value of LM in the equation above
ER + 7 = NP
Hence, the answer is NP = ER + 7
Answer:
..."one that can be written as a polynomial divided by a polynomial. Since polynomials are defined everywhere, the domain of a rational function is the set of all numbers except the zeros of the denominator."
