Evaluate 5x2–3(x–2)+x for x=3
2 answers:
The solution of 5x^2–3(x–2)+x for x = 3 is 45
<u>Solution:</u>
In this question we have been given an equation and asked to solve for a particular value of ‘x’.
The given equation is:
We have been asked to solve it for x=3.
So, we need to substitute the value of x as 3 in the equation and then simplify it as follows:
Therefore, on solving the equation for x = 3 we get 45

Answer:
The range of F(x) = logbx is the set of all positive real numbers is TRUE
Step-by-step explanation:
Given:
A function which logarithmic i.e F(x)=logbX=logx/logb with base 10
To Find;
Range belongs to All set are positive real numbers.
Solution:
The domain is function for which all set of inputs are defined and range for function is that set of all output that functions takes.
So Simple logarithmic function y=logbX is
So The functions has domain of all real values and range set of all real number.
In general the function F(x) = logbx where X>0 and b≠1 is continuous and one to one function.
logarithmic function is not defined for negative numbers or for zero.
And Also function approaches y-axis as x-tends to infinity but never touches the it.
Hence the Given statement is true
