ANSWER
The correct answer is option B
EXPLANATION
The equations are
and
When we multiply the second equation by , we obtain;
When we combine this new equation with equation (1).
We can see that has been eliminated from the equation.
We can then, solve for and then substitute the result in to any of the equations to find
.
Hence the correct answer is option B
The equation of g(x) is
Explanation:
Given that the function f(x) is
Also, given that the function g(x) is a vertical stretch of f(x) by a factor of 4.
We need to determine the equation of g(x)
<u>Equation of g(x):</u>
The vertical stretch of the function can be determined by multiplying the factor 4 with the function f(x).
Thus, we have,
Substituting the values,we have,
Simplifying the values, we get,
Hence, the equation of g(x) is
